improve the ease of executing a stunned enemy

When I'm up against four or five enemies, I might be able to parry one of the attackers and stun them, but even if I press the Justice button, it doesn't automatically lock onto the stunned enemy. I'm essentially tapping Justice while the other enemies buy time to attack me. The only surefire way is to select the enemy with the lock-on button and then press the Justice button. But in melee, it's difficult to quickly select the stunned enemy when there are three or four other enemies around. It would be really helpful to be able to press the Justice button and have the character automatically lock onto a nearby enemy to perform the attack, automatically running towards them to execute them.
