Road maintenace options

A function that will automatically lay a surface material for high traffic areas.
I love the detail in this game, the grass turning to dirt in high traffic areas has really helped me optimize layouts and see where bottle necks are. I apply a lot of concrete slabs to the surface to reduce vehicle maintenance, but the routes can change, and it can be tedious to keep up will laying it all out.
New settings to the existing maintenance buildings that adds the following:
Select your Material type
Default paint pattern
Minimum material on hand before starting ( To prevent eating up all of a resource )
Required Traffic volume per tile to auto surface ( 25%, 50%, 75%, 100% )
Normal settings:
Number of trucks assigned
Priority or work
I AM NOT A GAME DEVELOPER
However, I don't think this adds and 'new' code or graphics elements to the game, all the information and details are already in place, just a new way to use the data.
OPTIONAL:
Create a new "Road maintenance" building instead.

Maybe that could work with a new building similar to a mine tower, in which you'd set a type of the surface used, source storage, and number of service trucks.
