[Android 4.2] Backup Multi-User Data with Titanium Backup

I'm searching for a best practise to backup the App Data of my additional Users on Android 4.2.1. It seems that TiBa doesn't support the Android 4.2 Multi-User Feature so i've installed TiBa on every User. But TiBa everytime backups ALL Apps from all Users...so i must select single Apps to Backup (for every additional User).

This workflow is not a good solution. How do you backup Multi-User Apps & Data??
