How to restrict the dependent removal for a plan

For the Divorce life event under the Dependent Life plan, the expectation is that employees should be allowed to change their existing coverage options (i.e., coverage levels) and remove existing dependents, but should not be allowed to add any new dependents under any option.

The current setup is as follows:

Navigation: Program → Designation Requirements → Choose Plan Type → Life Events tab → Change Dependent Coverage Rule: Can Remove Dependent.

However, when the Divorce life event is triggered, the employee can select a different coverage option and submit the enrollment without providing dependent designation for the newly selected option. The system does not prompt for dependent designation for options other than the one previously selected.
