Is your feature request related to a problem? Please describe.
It's not a problem per-se, just a thing that would be nice to have, and would aid in resolving a slight issue with Pokecube.

Describe the solution you'd like
Some way to simply move a Pokemob to a different Pokecube, purely for aesthetic/item disinguishing reasons
It may not be faithful to the Pokemob games, but it would be very nice.

Perhaps it could be done by swapping with an identical Pokemob? Say you catch 2 of the same Pokemob in different cubes, you could switch which Pokemob is in which cube, so it doesn't affect the effort of doing so?
I don't want to give up a Pokemob I could have spend a significant amount of time with simply to have them in a different cube, but I really like how some of the different cubes look.

Describe alternatives you've considered
Simply dealing with it and using a different version of the same Pokemob to have a different cube

Additional context
With the way Pokecube does its Pokemob system, you can't easily see what Pokemob is in what cube, without holding the hotkey or just remembering what slot they're in.
Different cubes give a quick visual way to identify your Pokemobs, but you need to go out of your way to catch them in the desired cube.

My proposed solution wouldn't affect balance, as you'd effectively be wasting the special properties of the cube for the sake of aesthetics.

trading table does that, place a single (not stacked) cube in 1 slot, and your pokemob in the other slot, then press both trade buttons

Oh my gosh. Is this documented anywhere? Because that's great!
It doesn't allow you to reuse Mastercubes or anything by trading your Pokemob to a lower-tier one, does it?

No, the old cube is consumed upon swapping it to a new one
