ex-spouse for one state

Summary:

We have employees with locations in multiple states of USA. For One state we have the requirement to allow EX-Spouse also into the Medical Plan.

For all other state Employee's, they should not be allowed.

One way to achieve this is by a Post election Edit rule, another way is by creating another Option and underlying rates with Eligibility.

Is there any simpler way to achieve this.

Thanks
