Allow an added application to reside on an external drive for button customisation, instead of randomly removing it when manually added and configured.

Options+ on macOS is constantly removing an application manually added to Buttons and Point & Scroll section when the drive with the app unmounts. Not straight away, but at some point later on when the drive mounts and I launch the app my customised buttons do not work as expected on the MX Master. I then check in Options+ and I see the app has been removed. Please stop doing this.

I've even tried making a symlink to the app on the external drive and moved the symlink to my applications folder, but that stops working as well when the drive is unmounted and mounted after some time. Why so restrictive? Why even have the option to manually add an application in Options+ if you're not going to respect the choice.
