BuddyPress.org

I created my own group tab which shows my own page creation. I did this in a plug in. I would like everything in the group-header except for the tab to be hidden when my page is up. And then reappear when all the other tabs are up or active. Can I somehow bypass the group-head when I see fit with some kind of filtering or action? Or somehow redirect to my own version of the group-head? Please someone help me with this. I’m creating a plug in that might help everyone on buddy press.
