I tried doing that, but for me that is way too stressfull, especially if you get good hands on all tables.
Then again, I like to fold fold fold quick on zoom tables to get to the next good spot.
Do you do that as well, or do you wait for the table to prompt you?
Sorry if I didn't understand your question correctly, but I'll try to answer it based on a normal 6-ring cash game table...
I usually just fold the hands I would never play on a specific position (for example, I shouldn't be opening A4o from UTG, but this is an excellent option to use as a blind steal on BTN against SB and BB, according to GTO).
So I just fold the hands I would never use on the spot I'm situated in and wait to see what I will do based on what my opponents did before me (except when I'm the UTG, obviously).
For example: if I have an ATo on BTN and the UTG oppened with a mini raise, I'll just fold it, but if CO was the first to get into the game by doing a mini raise, I would 3-bet him, most part of the times, but I could fold it as well (dependind on his stats on the session and on the notes I have about him; I also could do this as a strategy of range balancement, to get closer to GTO, of course).
I can take these decisions quickly, most part of the times; this is automatic for me, specially because I'm well adapted to play on pre-flop due to the short stack and sped up games I like to play (Sit & Go, Spin & Go and turbo or hyper-turbo tournaments). I just try to take care about timing
tells against REGs or about miss clicks.
So you just need to train it. Start with a confortable number of screens and then you will try to raise the number 1 by 1 until you reach your goal. Also keep studying the game to make faster decisions while you play, actually, I could easily say that this is the most important thing you need to do if you want to play more tables without problems...
