VRP solver for planning multiple day routes

Overview of my project.

I have 600 sampling locations and 4 vehicles (150 stops per driver). The locations can only be visited between 8 am and 4:30 pm. Drivers have 30 minute break in middle of the day.

What i would like to accomplish are routes that visit the sampling location during time window then assume the driver continues toward next location, stays overnight and starts with next set of points the following day. I want it to repeat this until all 150 points are visited. I would also like routes to return to a specified depot during weekends if possible.

I have ran several attempts at this but keep getting violated constraints. It seems as though network analyst doesn't like that routes continue past the Specific Date that I set as a start date in the Analysis Settings.

Has anyone successfully created routes spanning multiple days with time constraints? Any help would be appreciated.

Thanks
