Hi there ! I discovered in the game folders many files with the maps of the game coded with numbers and letters

For example, the "tutorial" file :

:map 6
:tags tutor5
:scriptA tutorialbars -0.3 movey
:scriptB 6 30 zombs-spread
:scriptC 3 zombs-clump
:scriptD 2 zombs-clump
:size 23 16
:off 2 0
:tiles

00000211111111111112000
00000211111111111112000
00000211111111111112000
22222211122111221112222
2333331A1331A1331A13332
21111111111111111111112
211111111D11111C1111C12
21111111111111111111112
21111222222222222222222
21111233333333333333333
22222200000000000000000
33333300000000000000000

I guess 2 is for the walls but I never find in these files where are the doors !
Do you think this means in a future update, we will be able to create our own maps ??? I would LOVE to create my road to Canada and share it and play other players' map !!!
Peace out !
