In the short term, you would have to use Jeff's header attach mod and set the number of columns in the ACP to two (2).. Remove the anchor / hook from the header template and place it in the portal template.
That's why there has to be some changes made by Jeff because if you just copy the anchor to the portal, the colspan is too wide for the portal, and if you change it to two.. it's too narrow for the header.
Anyway it's Jeff's mod, and best left to him to decide how he wants to finish it, before chopping and changing things around to suit individual tastes.
