OMG YES!
Most animation and game dev software for 2D has something that can handle this kind of thing. It is definitely more of a hassle, but if we could get this until MAYBE you're able to do individual part images? I would still love you, LOL.
individual images just makes it easier, but right now I will settle for the possible =)
You get individual images export working, and I will buy every asset you have available now and in the future, LOL
If you can somehow space them out evenly like a 256x256 (per part) virtual grid or something, there's also easy spritesheet cutters that can take the pain of separating them manually also, then we can just use: https://isometric8.itch.io/sprite-sheet-slicer =)
