Suggestion: More Widget Areas

I was wondering if you can just add more Widget Areas to Appearance -> Widgets.

When I use the page builder, I like putting Widgets directly in the main content (and not only in the sidebar). I like mixing and matching different columns and stuff. But it only allows you to pick from the Widget Areas section.

I can trick it by putting extra stuff in the “General Sidebar” and use Home Page as an extra sidebar. But having more would be a lot better for the page builder.

tl;dr: Would like to put more widget columns in the actual home page with the builder.
