[Feature Request] Grid with Diagonals

[mjandren]

Is it possible to make a grid with just two lines bisecting the drawing into halves and quarters and two lines running diagonally from the corners?

I would like to use such a grid to try drawing by eye as in this video:

Currently you can only create Square or Perspective Grids. I think the idea to be able to create more options is a good one and I'd suggest adding this idea to the UserVoice page.
