Feature request: Start games from a position in variants

I don't know why, but you can't start a variant game from a set position, vs a person or a computer. This seems simple to implement cuz it already exists for standard chess. Thanks.

@programfox has a website with this idea. chessvariants.training/Variant960 you can adjust where each position start, making it even or asymmetrical.

@Zoinked I support this idea!
