changing the 'don't repeat in ..' for all the tracks with one click

[The Master]

Does anyone know how I can change all tracks at once from 10 days to 15 days? In other words, set the entire library to “Don’t repeat within 15 days” in one go.

Why don’t you use the global restrictions?
There is a global ‚Don‘t Repeat…‘ value.

The track individual restrictions are per track and you need to sett them per track. There is no global option to mass change them.

But see this post, it explains how you can do it: viewtopic.php?t=3906
