I tried searching and asking in game but couldn't find anything about it. I was wondering if it's possible to set a focus target while using a controller on PC?

When controller is enabled Shift+F doesn't seem to work, it simply puts an F into the chat box. My workaround so far has been to target the boss before a fight, switch to keyboard and press shift+f to set the boss as a focus target, then switch back to controller.

Anyways, does anybody know if there is just a different way to set a focus target while using a controller or if it just doesn't work as expected? Also, if anybody is unsure, I am Not talking about locking onto a target, focus target brings up a mini hp/cast bar by the mini map so you can see when the monster is casting as a healer with a tank or pt member as your locked target.
