It depends in part on how many combinations you have and what you want your output to look like.
In general, you will probably want to have some process logic executed on the entry and exit from the node, that captures in a TallyStatistic the time that the worker spent in that node. An alternative to a TallyStatistic might be a State array or simply writing to a file. That process logic could potentially be on either the Worker or on each Node.
I don't think we have a SimBit that does that, but you might look at ElectricVehicle and the Vehicle*** SimBits for some ideas.
