Hey everyone, does anyone know if it is possible to assign two provincial units to the same province ?

For example : Creating the "Sicilia" Province could enable the recruitement of Sicilian Slingers, AND Italian Foot.

I'm thinking about creating a new row in the UNITS.CSV and creating another unit tied to the ID_PROV_SICILIA_something, but I don't know if it can work ?

Not really, you can have one provincial unit listed per civilization level of the province owner though.
