Multiple packages with same source and destination

[Vensrc]

I have packages to be picked up from various sources and need to deliver them at couple of destinations.   When I run the algorithm, multiple vehicles are picking up packages from the same source which need to be delivered at same destination.    Number of packages from one source can be more than the vehicle capacity to bundle all of those packages with size dimension.  Is there any way to make a vehicle pickup all the packages from a source, which need to be delivered at the same location, if the vehicle capacity permits.

Please help

Thanks
