Assign candidate to recruiter not owning the req

We do a lot of talent pool recruiting and many times a different recruiter will work with a candidate in another recruiter's req. It gets very difficult to manage candidate process since that active candidate doesn't show up on the homepage for the recruiter working with the candidate (only the recruiter assigned on the req). Is there a way we could change the recruiter assigned to a candidate, without changing the recruiter in charge of the overall req?
