Minor piece endgame puzzles

I enjoy solving endgame puzzles, especially custom ones. I'm worst in minor piece endgames currently, so I would like to ask if you could add knight and bishop endgames as options in custom puzzles?

Puzzles only support single solution puzzles, which are generally forcing. Positions where messing up once could still result in mate aren't good for the format.

There is the option to practice against a computer for those positions under the Learn option. Probably under Endgames but may be under Practice

The main downside of that is I don't believe the engine is tied into the tablebase so won't play moves that maximize mate depth.

I'm quite versed in general principles of knight and bishop endgames, since I've read quite a lot of endgame literature and I'm not looking something like practicing non forcing variations with a computer since I'm doing it elsewhere. What my question was about is forcing bishop and knight endgame puzzles. There are a lot of them currently in the puzzle solver but there's no option to choose them in the custom puzzles option: You can choose for example pawn endgames, rook endgames, etc. but you can't choose knight endgames nor bishop endgames. I would like to have this feature added. This feature exist in already on Lichess but not on chess.com.

There's some changes being made to the puzzle theming system. Not sure that is something being included in the current work.
