Visually available heroes

Hi, when a battle takes place, during someone else’s turn, when minions hit, buffs / debuffs are applied, often it takes quite a long time, all my heroes continue to be visually available for pressing, this repels and misleads. Is it possible to somehow visually show that the hero cannot be used at the moment?

Maybe fade them out a bit until they are available to fire?
I feel your pain…
