Can't add multiple KnownPluginLists to a menu

In my pMix app i use two different KnownPluginLists, one for real plugins and one for FAUST .dsp files. which are JIT compiled (which i use PluginDirectoryScanner for also). It’s a shame that KnownPluginList:addToMenu() always starts the index at the same “menuIdBase”, since this means I can’t add both of the KnownPluginLists to a menu.

would be great if KnownPluginList:addToMenu() could start IDs from the highest found in the existing menu (for example) so that I could do this!

Bit of an edge-case, but please feel free to suggest a patch that’d do what you need!
