Re-ordering or sorting the "active tilemap" list in the Tile Palette window

Is anyone else frustrated by the fact that we cannot re-order or in any way sort the “active tilemap” list in the Tile Palette window? With enough tilemaps, it gets unwieldy very quickly.

If Unity won’t provide this simple fix (maybe just alphabetize the list!), is there a coding solution to this? Where should I be looking and what should I be editing to write my own custom code to do this?

Would like to bump it. When using lots of tiles this feature is really really important. Any news about this?
