Adjustable Background Grid for squared A4 Paper Like Format

Hi,

I use Miro for distance Learning in math or Physics, therefor it would be great if it would be possible to change the size of the Background Grid (not the Table/Grid widget). Currently the size is constant and if you choose an A4 frame the size of one grid square is like ¼ of the page, instead of ~5mm (like a squared DIN A4 Paper).

This would be a huge development for nicely formatted A4 documents.
