1BigOT, it will depends on a program you asking about. Please next time mention in your question which program it belongs to (we are discussing three different Captions in this thread).
1st thing can be done in 888Caption and StarsCaption, 2nd thing can be done in StarsCapiton only.
Answers for StarsCaption / Table manager 2:
1. Add Regular slot, turn on Stack for it. Add two Activated slots with Stack disabled.
Configure Activate table at / Your turn, Deactivate table at / End of turn.
2. It is possible to have several stack with independent table activation at your turn, see Multi-stack activation mode
here.
