That would be a useful feature!
Personally, I use Yanfly's Enhanced TP to limit the player's maximum TP to 3, disable any TP gain or regen, then give each card a 1 or 2 TP cost. I also use Yanfly's Base Troop Event to make sure the player gains his max TP back each turn. When the player levels up, I use Yanfly's Enhanced TP's notetags to change the TP mode to another one with higher max TP.
Oh, I also changed the name from TP to AP. Gotta make it look as though I know what I'm doing :)
It's a massive (and almost ridiculous) workaround, but I couldn't think of a better one hahahahha
