I want to use the same project layout for two different pages, it won't let me use two different amounts of columns

What do I need to do to use a 3 column Grid: Overlay layout for my Editing page and a 2 column Grid: Overlay layout for my Photo page. When I change one page's columns, it changes both page's, rather than simply the one I intended to edit. The only way I have found around this is by using a different layout, which I don't want to do. 

I'm very new to squarespace and will take any comments, even if it's not about this specific issue! thanks!🤖

Hi,

All pages will use same column layout

You can set 3 in this page, then share link to photo page, we can give some simple code to change photo page to 2 columns.
