I have used Reaper as my audio DAW for a while. PowerDirector's interface is nothing like it, and I must confess that it appears to have shortcomings in how certain tasks are performed. For example, activating the mouse wheel in Reaper results in a change in the project scale, i.e., a zoom wheel. In PowerDirector, mouse scroll wheel moves you forward and backward in time, which means to change the project scale one has to use the bar at the bottom left of the screen. I do a lot of zooming in and out, and I find it very tedious to use this bar. It would make much more sense to be able to use the scroll wheel to perform this task because it is faster and simpler.

Is there any simple way to reassign function of the scroll wheel for PowerDirector?
