Please add customizable ruler measure units#2695

Current rulers might work for wargaming minature games, however a lot of roleplaying games are still left out as there is no ruler that counts each grid square as 1.5m or 5ft and they seem to be hardcoded that there are not scripts capable of changing that.

Can we get a window for the Grid measurement unit that allows us to set how much of a given measurement unit is each square on the grid? That way everyone can customize the ruler to the needs of every campaign. For example setting each square as 5ft for 5E combat maps or each square as 10 miles / 16 km for world maps.

If the previous is too complicated, could I at least request for ruler measuring units that counts each grid square as 1.5m and one that counts them as 5ft each?
