First time I've heard someone mentioning team training, do you really use it?
Regarding the initial question. People have mentioned already that you should plan ahead in the future, and train a 2 pos training(I mean the ones with no single position option, rebounding and 1v1 g/f)
But another idea is to have two main trainees, and a whatever third one(this is for messed-up-minutes situations during the season). You can just train those two guys during ASW, and stick to the presumed 1 position training plan.
