Hey TortoiseMaximus. I think for now it is not possible although it may happen sometime in the future. There are two related threads you can check. Cheers.

Hi,
Is it possible to host a tournament with a custom starting position? Maybe I'm bad at the internet, but it seemed like the Create Tournament screen only gave you a drop-down list of openings to start from. Sometimes I'd like to be more specific about the variation to be played.
Thanks in advance.
