Limit Total Working Time


could you please push tie in the right direction for including a restriction of the total working hours (driving time + service time). My tours could be quite different as in ode having a lot of shipments on a very short driving time, others very long driving time and only a few shipments. It should be possible to limit it to 10hours total.
Using the earliest start and latest end also doesn’t work because on truck could start very early for long driving time, the other one could start very late, depending on the time windows.

Tanks in advance
