Overlapping subscriptions

I am trying to change my region as I moved from the US to Europe, and some "local" apps are not available on the US app store. But I have quite a few overlapping subscriptions, which seems to make this very difficult. Most of them are yearly ones, and don't expire at the same time (not even close); if I wanted to wait out while all of them expire, I wouldn't be able to use some of them for months, which is really inconvenient because I need some for work (like Office, but then also iTunes match, and a lot of iPad apps.).

I tried to search for this but couldn't find: is there a way to end and restart all subscriptions at the same time? How? I'm sure this is something a lot of people who move have an issue with...
