'Rules > User Agent > Custom' does not save the user agent when I disable it

I would like to toggle a custom user agent (Rules > User Agent > Custom) off and on to compare the differences on a webpage. But when I choose disable (Rules > User Agent > Disable) if I then go to turn it back on (Rules > User Agent > Custom) what I previously entered is gone.

I'm using Fiddler v4.6.20173.38786 (Built: Friday, September 15, 2017).

    Thanks Eric I will try that as a workaround the next time I want to toggle back and forth.

    This is unfortunately inherent in how the %CUSTOM% token works for RulesStringValues.

    The simple way to deal with this would be to just add your new UA string directly in the script itself (Rules > Customize Rules, see the lines under [RulesString("&User-Agents", true)] )
