Is there a way to display 2 different grids in layout view?

I'm making a metroidvania game, and the camera snaps from screen to screen, just like most metroidvanias. That way, it would be very useful if I could display two grids at the same time, one 8x8, for me to place the general objects, and another one 240x135, the size of the screen, or one zone the camera snaps to. If this isn't possible, is there a way to at least display an 240x135 grid while snapping to an 8x8 grid?

What you can do is place a tiledbackground object with 240x135 rectangular image on your layout. Set it invisible and lock in the editor, and use it as a grid.
