Hi Marshae,
Thank you for writing in, yes that is possible, what you need to do is create another header and assign that header to http://www.abc.com/members page.
If you already have a header that is built-in Header builder, then you can duplicate that header and modify it and assign it to a specific page.
Header and Footer Builder Overview
The idea is to have two headers, one as the Global header and one as the header of the specific page.
If you want to learn more about Header Builder, please watch our Better Headers Tutorial series on our channel.
Have a nice day,
