EAC Tools allows you to easily create a unisex mortality table. This accomplished by blending a male table and a female table, where each table is weighted by a factor. For example, to create a unisex table that is based on the 1983 Group Annuity Mortality table, 60% male, 40% female, the mortality table parameter would be:

GAM83M[.6]^GAM83F[.4]

Alternatively, you can create your own table of qx values, blend/combine/project in any way you wish, and create a custom user-defined mortality table that you can reference using your custom table name.
