You can edit using the inspector.
But you may be referring to the problem I am currently having with live.menu.
As far as I can tell, you can't 'load it on the fly' like you can umenu.
For instance, you can have midiinfo 'bang' a list of MIDI devices into umenu for selection.
But I haven't been able to figure out how to do that with live.menu.
Anyone have any ideas?
