Removing a Shape from Document by VBA

Hi all,
I have a document which I receive on a daily basis and I have to edit the header each time.

Is there a way I can first remove the shape around all of my text pages (excluding page 1), because while that shape is there, I can't really edit the header. I am using Word on a Mac. 

But is it possible for me to remove the shape from certain types of pages and not from other types?

Can all this be done with a Macro?

Appreciate the help,

JH
