Header wider than master page content

[CilonX]

Hello, 

Is it possible, in AEM Form Designer, to make the header (on the first page only) wider than the master page content?

So like Header will be 100% page width (only on 1st page) and the rest of the form to have normal margins.

Take 2 master pages, on the first master page take your wider header and on the second master page other header.

And restrict the first  master page occurrence to first page only by setting the master page property " Restrict Page Occurrence" > Min Count to 1
