Add Social Security Field for Spouse if not Informant or Primary Purchaser

Currently only Friends and Family marked as Primary Purchaser, CoPurchaser, or Informant will have the option to enter their social security number. Sometimes, the Spouse is none of those roles but we still need to add their social for certain forms like the Death Certificate and SSA-721. Can we please add a Social Security Number field for either all family and friends or just Spouse, Wife, Husband, Common Law, etc?
