How would you configure Infuse to stream from a local network drive but fallback to a Google Drive share?

Let’s say you have a local network drive with your media collection which mirrors itself to Google Drive for offsite backup purposes. If you had a local network drive that you primarily used to view Infuse movies while at home, but when you went on the road you wanted to fallback to a Google Drive config (since streaming from Google’s servers would be much faster than streaming from your home server) how would you accomplish that?
