Custom User Title not override user title


Is there any way to make the Custom User Title not override the user's regular use title assigned by his group or set it up so that both the custom user title and the highest display order group's title is shown?
I didn't see it in any options so i figured i'd ask if anyone in here has coded a way to do it.
If not, could anyone point me in the right direction in terms of how to do it?
