They only way you can force someone to come back to a particular viewpoint in a full 360° video is to cut the clip on the timeline and then set a new starting view. You can do this with a transition, which can smooth the (potential) position shift or you can clearly bring it to the viewer's attention.
If you want to show the viewer a specific "route" through your video, you'd want to produce to normal 2d video while using keyframes to keep the interesting scences and objects visible.
Thank you for your reply - I did find another way to fix the "spin drift". I turned off the 360 view and placed the video on the timeline, I then used start and ending keyframes to shift the video horizontally, keeping the original centre point in the middle of the screen.
I then added a duplicate video on track 2, and set its starting keyframe offscreen, but touching the edge of the video in track 1. Next, I added the ending keyframe to finish still touching the edge of track 1 (which would now be offscreen) as it moved horizontally.
I then rendered the video in 360.
This workaround does the job, but does leave a slightly noticable stitch line. It wouldn't work for "horizon drift" though.

Thanks Ash for confirming that PowerDirector currently does not currently have this feature.
Hopefully PowerDirector will consider this Feature Request for an upcoming version upgrade.
i.e.
Clone the "360 Start View" metadata functionality to keyframes, allowing adjustment of X Y Z rotation metadata on any keyframe in a 360 video (and as a bonus, with a smooth panning function to the new X Y Z view would be excellent)
This featureis ideal for the project I'm working on. We are just at the beginning of a multi-year project which begins rollout next week to the first five end-user sites (with dozens of presales in the pipeline, and hundreds more expected over the next few years).
We are not using VR headsets, but playing 360 video on a TV.
The user presses the "walk" button on a controller, and our javascript 360 video player automatically re-sets the X Y Z back to whatever the default "forward view" is encoded in the metadata, and the video plays.
The only time the user is allowed to pan/tilt the view and look around the 360 image is after they have pressed the "stop" button, and the video is paused on a single equirectangular frame, and then they can look around.
When they press the play button again, the video will re-center the X Y Z back to wherever the current "front direction" was set in the metadata during PowerDirector video editing.
The ability in PowerDirector to add a keyframe to a 360 video, and change the "forward view" metadata (X Y Z rotation) is a feature I would gladly welcome in a future upgrade.
P.S. If anyone knows about any other software that might allow adding multiple X Y Z metadata settings in the middle of a 360 video then please share your knowledge.
I am desperate for this to become an option too - I have a GoPro MAX, which has had a drifting problem that could be fixed using the method mentioned above... On my longer videos it's really noticable that the footage slowly tilts on the horizon.
I have updated the firmware a few times, and now I have the problem of the footage slowly turning on the x axis when using "World Lock"! At the start of my 8 minute long clip, the video is facing forward, but by the end of it, it has spun a full 180 degrees...
If I could set the starting position, and then use a keyframe at the end of the footage to correct the spinning/drifting, that would be amazing. (I wouldn't need to do this if the camera worked correctly in the first place though!)
