Finding Empty Key Commands/Mastering KC Layouts

So basically I’m switching most of my MIDI Logical Editor Presets over to OSC control via Lemur.

I need to figure out some organized way of doing this instead of going through keys for each editor command until I find one that is open.

This really applies to KCs and macros for all DAWs.

I’m just wondering if anyone has any tips or insights into this.

Thanks!
