Re-posing an stl file that consists of split parts

New to blender.

i have an stl file I want to re-pose in blender. This part seems easy, edge mode, select edges to make the joint, mark it as seam, then move things around.

The problem is the model I want to repose is broken up into like 10 different parts. I could assemble it into a single model in microsoft builder then proceed but i would like to un-assemble it back into individual socketed parts after re-posing.

is this possible to do in blender or is it not worth the trouble for someone new to blender?

thanks!
