Repair Shops at mechanics

Since we can only get engines repaired up to 75% without going to a mechanic, it really limits everyone when a mechanic shop is not open.

Can we add repair stations at the mechanics that is available for the public? The prices can be higher than normal repair shops and the money can go towards the mechanic business as extra income. The repair stations should only be placed at the mechanic shops that are open the most frequently and could require storage of repair kits/adv repair kits to prevent collecting passive income from the closed/inactive shops.
