I'm sorry that wasn't what you had in mind.
One way or another, you'd need to re-order them one by one anyway. Whether it's in PhD or Windows, it would still be a decent task.
You'd probably find that renaming software would help make it easier, and save you a lot of time. I user one called "ReNamer" but there are quite a few free ones available. I use it for similar purposes to yours - to get photos grouped & ordered for inclusion in a presentation.
Not exactly sure how you have the 4 camera shoot photos organised at the moment, but I:
a. put them in sub-folders
b. rename the files in each folder (using ReNamer) - prefixed to reflect the required order
c. import all the photos into the project.
