Importing Animations (VRM4U)

I’ve created several VRoid Studio models that I can import into Unreal Engine (5.3.2). I already understand the process of doing the importation, however, when it comes to the Animations, I would like to know do I have to Retarget the animations for each and every model I import, especially if it’s using the same skeleton? It seems a bit redundant to duplicate the same set of animations (for like 100 animations). The only difference is some of the models are different heights, and some of the clothes and hair have more/less bones, but the core movements shouldn’t affect those three things, right?
