Is there any way to increase the party health tab?

Currently playing as a healer, I find it a pain to have a small party tab. It seems unchangeable through the usual customization process. But, all too often, I accidentally click on the wrong health bar and that costs someone their life.

I was hoping that someone knew how to increase the size of the health bars. If not, I might want to start practicing targeting with a keyboard config.

Thanks for any help.

*EDIT: Nevermind, got someone to help me in game.
