Arena: can we have an option to forfeit after team is assembled

prior to entering arena, sometimes you have such a team of weirdos, and arena lags quite a bit after forfeit. (with all the talk etc)
Actually for me after forfeiting on 1st turn its frozen.
Its not actually frozen - everything moves, but it doesnt respond to any keys, think it tries to reproduce some babble from that arena guy.
Can we also have autosave after finishing the arena, guess ive lost quite a bit of progress. at least with 5x wins.
