Nested animation clip menu in Animation Menu?


So, as you can see, I have a LOT of animations in a single controller (I’m making a top-down roguelike with lots of dynamic animations/movesets):

Is there any way to get the animation clip menu to nest things? This would HUGELY help my QoL :grimacing:

I can get the menu to nest if I manually change the animation file’s internal name to have "/"s instead of underscores - but this causes Unity to give a warning that the file name does not match the main object name, and searching this issue indicates it can lead to build failures!

Is there any way to get the unity editor menus to treat “_” (or another usable name) as a nesting character?
