Share animation to multiple character with similar skeleton?

I have 12 humanoid characters in my game. All 12 characters have different height and body type. They all got their own skeleton and skin binding. The skeletons are basically identical with names and number of bones, it just the height and location that is different. So essentially they all have the same skeleton. How can I share animations for all characters using animation retarget? I have been reading the documentation and it seems to me that you have to tell UE4 which bone is which but they all have the same skeleton basically. Is there a way to just make an animation blueprint that allows you to use the same animation for multiple skeletons/characters? Tutorial?

Did you ever find this out?
