Anyone know how to make modded interiors only spawn on modded moons?

I enjoy Wesleys Interiors mod with the Wesleys Moons mod in our playthroughs, but lately we've been missing the vanilla interiors as they spawn to infrequently now. We tried looking in the config file but couldnt seem to see any way to turn them off for specific moons. Does anyone know how to make modded interiors only spawn on modded moons?
