Capsman avoid channel

Is there a way to configure caps to NOT use a specific frequency?
Trouble is that in a small area the 5500MHz is not working (near the fridge in a meetingroom), and the nearest AP tend to select exactly that channel when set to auto. The result is that devices try to connect to that AP, get disconnected, jump to another AP with weaker signal and at some point decides to go back to the strongest AP, get disconnected, and this keeps looping.
A workaround is to set channels manually, but I’d prefer if I could set something like “auto except 5500”. Is it possible?

Do you think about this?

That would require to enter all frequencies, make a full list of frequencies for the country. I was wondering if there was a way to say all EXCEPT the one specified.
