Guidelines: Add quick selection between "for all pages" and for "current page"

I've been using CD since version 3... have learned a lot over the years and still do. For me in the field of advertising technology it happens again and again that different page sizes have to be created. If I already create guides on the start page, I either have to edit them to only assign them to the first page or I have the guides on all pages, which is an advantage for some projects. Couldn't this be integrated by clicking between "for all pages" and for "current page"?
