functionality for client to reset offer so candidate can go through offer auth again

Service Desk and clients have no access to reset an offered candidate, who has already been through auth and offer created, back to go through auth again.

A candidate goes through offer auth, is fully authorised and offer is created. The candidate may want changes to what they've been offered and client has to go through auth again - there is no way for this to be done apart from 2nd line resetting.

Would be great if candidate could be reset back to 'further action required' in interview feedback.
