If yanfly action sequences allow for calling skills in between sequences, you can try calling the skill in between the sequences itself and only use one (1) input. Otherwise, try calling via a script call or common events using force timed attack in between the sequences and see if that helps
Sorry for the late response, i tried both methods and the button input prompt shows up but damage calculation doesn't work, it straight up shows no damage numbers even when successfully putting the correct inputs.
