When you click-drag-import an fbx that contains, let’s say, 4 takes, you get 4 auto-named animations. And if you reimport any of these, the uasset “knows” what take name to reimport, even if you reorder the takes within the source fbx. It “knows” even if you rename the uasset. Where in the uasset is this information stored and is it accessible, perhaps to change directly if necessary?
I dont know the fbx file format to be honest. But i wonder if UED imports them in the order they are saved inside the FBX file? Then UED just does the same.
Be interesting if there is a tag or id in the file and UED stores it
hopefully someone else will know

Have a look here, maybe they have IDs:
