Enable/disable MIDI learn on an I/F object from another I/F object

[ahonoe]

Hi Gurus,

I'd like to use a button named "assign" to enable the MIDI learn on another button in Hollyhock. Is this possible? (I know I can do so from Hollyhock's toolbar but I want use a button to do so.) If so, how is this done? I don't see a parameter input to do this in any I/F objects.

Thanks!
