Option for videos to search external folder before streaming

I’d like to request the ability to set an app to look for videos in an external folder, and then go online to YouTube or another source if the video file isn’t found. I thought that was possible in earlier versions of SAB, but after some recent issues with an app I built found out that doesn’t seem to be the case. This would be very helpful to make one version of an app that could work for both offline distribution through SD cards and online distribution through the Play Store, rather than having to make 2 separate versions.
