Add hotbutton to group window

[Bigpardon]

I have noticed the great group window UIs from ger et al. There seem to be some hotbutton along the button for follow, assist, etc. It is possible to have two or three blank so that another hotbutton can be dragged-and-dropped into it? For example, my main heal and main ward can be right beneath everyone's name in the group window.

Think it might be kinda cool expecially for a class that doesn't focus just on the mobs but rather on the group members.

Thanks,
