MIDI Learn without controller?

Hi there, I’ve been experimenting with Note Expression (finally) and it’s awesome, but the number of parameters I can assign to a NE slot is pretty limited. If I want to control stuff like waveform type or LFO rate I have to use MIDI. Trouble is, I can’t seem to assign MIDI CC’s any other way than by turning a control on my keyboard, and I’m not always at mine (laptop setup, frequently travelling). Is there any way to manually type in a CC number? Thanks!
