I think a Type=100 Replenishment would work fine, and wouldn't necessitate any campaign files. It would be a "Merchant", technically, but fly the Rising Sun flag (I think - maybe)... It would be like the sub tenders or fleet oilers - but, it is your mod, so what you decide to do is what should be done, not what anyone else says. Anyone who wants to use your mod can change things, if need be, to make it work with their other mod(s). But if you want to supply "historical" routings, then what you have in that picture would be a way to go with it also. I don't think though, that you can arbitrarily add another Type= category. We tried that ourselves before with FotRSU, and I cannot recall off the top of my head, the mayhem it caused, but maybe s7rikeback can remember... ?? just be careful of that idea is all I'm saying.
