Grid per floor scale

This is something I cant find in any map making apps.
Having a grid that scales for each floor instead of only one grid that wont reflect height differences.

Having a grid for each floor would help a lot on the hight perspective perceiving.

The trick part, at least in my mind, would be to hide below grids under superior objects and construction and not show upper grids when there is no floor in them, allowing to see the bellow grids in this case.

Lets supose I have created a mountain map whith multiple height levels.

As the levels go up, the squares in the grid should grow accordingly to reflect the height perspective difference.
