What do we do in the instance of being interested in multiple roles? Specifically, I'd prefer to have Asch signed up for the final confrontation, but I would also be happy to have him take on one of repair teams, and ICly he would prioritize low-manpower teams over joining the definitely-going-to-be-full attack team.

Would it be better if I signed up for all of the rounds I'm interested in now, or waited until closer to the shuffle date to pick just one?
