Focus Fire on PS5

There is a problem with focus fire for spells on the joysticks. For example, cold snap can cause a blast of ice on a frozen enemy or a frostbolt.
But it is almost impossible to attack frozen balls with cold snap, because targets are selected.
But there is a bug with the fact that when the boss is frozen, you can stand and bite cold snap many times, and he does not attack the boss, because he will focus on something behind the screen.
Switching focus modes does not help in any way.
We need some kind of third focus fire mode for target selection for spells and frozen targets.
