Challenges with the self-reported life event enrollment window or flow

Summary:

In Redwood UI for Benefits and the challenge we are facing with employees reporting events like e.g.

-Employee reports a Marriage event (which has 30-day enrollment window) on 28th day by attaching Marriage certificate
-Admin reviews the certificate and approves on day 29th.
-Employees sees the approval email on day 30th

So, then the employee has only 1 day or so to enroll (assuming Benefits admin approves it timely) into benefits and causing conflicts.

Instead of this seeded flow:
Can we have employee proceed with enrollment (while the admin is reviewing the certificate) so that they don't lose window while approval in progress
