How to assign cv in back to chord select?

Apologies if I'm missing something obvious here. I haven't been able to find a clear answer to the following question:

It is great being able to assign cv in to different parameters wiggling the corresponding knobs. But it is not entirely clear to me how to revert the changes and assign the cv in back to chord selection. The manual doesn't seem to specify this either. Can someone please help?

Thanks!
