Custom header for a tab group

I’ve looked all over for this info but I’m just not seeing it.


I have a tab setup and for every page that falls inside my “Challenge” tab I want to have a “settings” button in the header which takes the user to ‘tab.settings’

In tab.settings the header will be bare.

What I’ve tried:

I’ve tried adding the header button to my tabs.html
I’ve thought of adding a “header template” to all the tab.challenge pages but I like to think there is a better way.
