Is there a way to see the Window size over the full layout s

I currently have a window size on 1280x720. I love the grid so you can see the first window.

Talking about this one

Sadly this is only in the top corner, is there a way to get this grid over the full layout? (I am not looking for "Show grid" as its not the same).

Currently I have made backgrounds that show the tile but I wonder if there is any other way? Maybe smarter way

I don't know any setting in the editor that would let you do that. Why would you need it anyway?

I find it perfect when I make different zones, so when you move between zones the thing you see changes, I have been doing this instead of having 50 different layouts in a game

I could see that being useful for those types of projects!
