It's a bit unclear to me what you're trying to accomplish here. Is this for your progressive that has teams draft 29 players and keep 4 of them in AAA? If so, you won't be able to do it through the manual AAA tool, since not all players will show up as draftable AAA prospects (not 100% sure of that, but believe it to be the case). I'd guess that support could add 4 players to each team's roster via ticket.
When you say you "don't want the non-drafted players to be ringers" are you talking about additional AAA players or the 4 extras each team has?
