I was considering a "master template" faux campaign that would catalog all world's navies, their bases, and rough organizations for a given period, say 1910-1920. Once this existed, a campaign designer could erase the navies he doesn't want (or imports them into a fresh campaign). This would be a neat resource for a future
Feature request: "Import location" similar to "import division".
That is pure genius! It would make it very easy to build hypotheticals. Particularly interesting with nations like Britain who had a lot of their force spread around the globe and Russia with the sea-locked Black Sea fleet.
I was thinking about adding the Black Sea theatre as an addition within the Baltic Campaign as a way to see how to get it working and so that the existing divisions remain intact.
