Copy / Paste Plug-In Settings

I don’t seem to be able to copy an insert plug-in settings to the very same plug-in run as an offline process.

If this is correct I’d like to be able to do so. Sometimes I set up inserts because it makes sense for me at the time, or because I find it easier to audition settings that way, and then change my mind or move on to apply it offline. Currently I have to save settings and then load them, which just bloats all the saved plug-in presets.
