Yes, this has been discussed a couple of times here, and raised as a feature request
There’s also been discussion of a work around, but it means sacrificing a midi input.
@Giedrius - I think being able to manually enter midi mappings will make things easier for many users. That said, things would be much better if we can manually enter a virtual pipe as a cc source as well as the physical inputs. This would enable a kind of preprocessing of CC data inside the midihub prior to mapping that would unlock some seriously poweful functionality … If that were possible that would make my day
