Trip Routing

I would prefer to be able to include empty miles back to the shop and/or next load point after the drop off. 

for example...

(1)Driver loads at point A...

(2) Driver drives back to the shop

(3) Driver makes delivery

(4) Driver goes back to load point

Functionality to simply change the order of the route pick-up, drop-off, and in transit stops on the load page would work nicely.
