Can you sync the songs that are on Anytune on your iPad with Anytune for Mac on the computer so that you don’t have to do each device/computer individually?
Anytune will let you export (backup) a copy of your song settings and marks to iCloud, and then reimport them on any of your other devices. This works between iPad, iPhone and Mac.
We have a demo video of this on iOS, but the Mac version is very similar.
