Adding "don't Save Vst Plugin Parameters" Radiobox

I use a couple of demo VST plugins, they are really nice, but some pop up a dialog mentioning that “saving banks” or whatever parameter settings are disabled in the demo version.
This also happens when i save a song…I have to go outside renoise (off-focus), click the dialog away to have renoise continue saving the song.

With Autosave this event is even very irritating.

It would be nice if i could check a radio-box in the VST configuration frame of Renoise, offering the toggle not to order the VST plugin to save it’s internal parameters .
I know most rather do save the plugin’s parameters but in some cases it’s better not to.
