I see some do that manualy, group 3 digits together, display the value (so 1234 would display 234), to the left add a combinator /1000 and display the number to the left (1 would display XX1)
I thought of this, but cramping 3 digits in a single tile is a bit much and unreadable, I tested that already... I can't extend to two tiles, as that would mess up the logic that is making it so efficient. I'll think of a solution, but don't hold your hopes up...
