University Health - Critical Illness benefit

For University Health we implemented SSO for Critical Illness benefit but we do not store coverage tier for the enrollment. We need coverage tier to send the right deduction codes.

1. Can development check if we can fetch coverage tier while fetching other enrollment related data?

2. If not then we need to add a UDF on employee demographics and write a trigger around it to get the coverage tier for Critical Illness benefit.

Please talk with me if we are going with option #2.
