Action Times+ and Sealing Skills

Hi,
I currently am using action times+ to give my actors 2 to 4 actions per turn based on states they have. While I want them to be able to take multiple actions per turn, I want any given action to only be usable once that turn.

In essence, I want the skill to be sealed after an actor selects a target with it, but before execution. Is there any way of accomplishing this without major rewrites to the battle system? This would mean that if an actor has 2 skills -- skill 1 and skill 2 -- they can select skill 1/2 as their first action, and then only skill 2/1 as their second action because the former skill is now sealed.

Sidenotes: I know that yanfly's cooldowns plugin and limit skill uses plugins both can have this effect of limiting a skill to one execution per turn--but my issue is that they do not prevent users from trying to use the skill multiple times. It leads to feel bad moments where players feel like the UI is lying to them and they waste extra actions.
