Is there any way to dossier regions that don't exist in the same way that you can dossier nations that don't currently exist? I know you can do it with nations that have CTE'd and I think it is possible to do it with nations that have yet to be created through the Advanced Dossier, but I cannot find any way to do this with regions.
Note: There's not too much of a point to it other than maybe watching to see who refounds certain regions that Ceased to Exist, I guess. I'm just curious to see if there is a way since the Advanced Dossier is limited only to nation lists.
