When using Relentless and Cruel during someone else's turn, usually it is the case that you'll choose to re-roll in order to win. It would speed up turn based games if the player had the option to set this as default behaviour at the end of their turn.
Dangerous could also benefit from something similar (perhaps "engage if attacked by these numbers"...).
