Is it possible to play humans from different starting positions for 2 player chess?

I know it's possible to play the computer from different starting positions on this site, but was wondering if it's possible to play humans from different starting positions on this site, including starting positions that have more pieces than in the default starting positions for 2 player chess?  Could I play humans from this starting position for instance?

Or alternatively this one?

Or perhaps even this one?

You can play custom setups in Daily, though I don't know how drastic you can get.

Is there a way to choose what color to play as during a game?

Yeah

How do I pick the color to play during a game?  I couldn't see a way to pick the color to play during a game.

You can only choose color in unrated games.

Yes it is
