Spouse life insurance for same sex spouse

We are configuring our health/insurance plans to allow same sex spouse as a dependent/beneficiary/enrollee. We were advised to create a new subtype for family member called ‘Same Sex Spouse’ rather than just using the existing ‘Spouse’. The problem we are running into is on our Spouse Life Insurance. SAP only allows costs to be determined based on the age of either the Employee, the Spouse or the Domestic Partner. We are not able to choose the new Same Sex Spouse. Has anyone found a way around this? How is everyone handling Same Sex Spouses (for legally married spouses). Are you just using the existing Spouse relationship? If so, has that caused any issues elsewhere?
