Please fix Autocreation of Future Stages with No Deadline

Description - When a "Read Only" viewer accesses a Proof, the system creates a new Stage with "No Deadline." This causes the Proof to be showng as having No Deadline in our Reporting.

Why is this feature important to you - We need to be able to accurately track and report out on our Proofing.

How would you like the feature to work - We would prefer that the New Stage not wipe out the Proof Deadline in Reporting.

Current Behaviour - The current behavior is that the New Stage is listed with "No Deadline" and so then the Proof appears with "No Deadline" in our Reporting.
