For example, I add "Google Maps 7.7.0.apk" and "Facebook 7.9.apk" into the repository. Days later I upgrade only the Facebook app to "Facebook 8.0.apk" and I keep the Maps version (as a newer version may cause gliteches in some of my phones), so in all my phones, Facebook gets automatically updated (via a WiFi connection if possible) but Maps doesn't.
Would it be possible? The number of apps would be much large.
Thanks in advance.
