Problem in sizing 3 way Valve fisher specification manager

Dear Friends

As you are completely aware , three-way valve bodies having three flow connections, two of which can be inlets with one outlet (for converging or mixing flows), or one inlet and two outlets (for diverging or diverting flows). in both case we have 3 connection. but when I start to size valve with Fisher Valve Specification Manager (Sizing application), and select three way as style in installation data tab , I could not find any items related to entering data related to connection ( nominal Pipe Size , End connection) and only there are one inlet pipe size and one outlet pipe size. moreover ratio combination can not be found.

Dear Experts please guide me about mentioned issues.

Thanks in advance
