Change filemask name in Android app?

Hi,
I have used the iOS app since the beginning. Now I helping my sister who recently moved from iOS to Android to get AutoUpload to work as good as it works for iOS. I have read that sometimes the auto upload has some problem but it will probably be solved in future releases. The function I want to find in the Android app now is the function to change the file name on the auto uploaded files. At the iOS app I used the YYYY-MM-DD hh-mm-ss and filename mask and want to use if for my sisters Android now also. Any suggestions?
