Are there other options for reasons to archive requests?

For example, I had to turn down a request because an owner also had cats, and I am allergic to cats. I noted in the archive reason “owner didn’t work out.” I also archived another request and had to state “Dog didn’t work out” but it was because the dog had separation anxiety and couldn’t be left alone when I had to go to work. Otherwise, I would have sat for the dog. Can there be more options or a write in or something?
