ADS_SPC_IF problem while importing pspice file into ADS

I have encountered a problem when importing pspice model of GaN transistor EPC2015 into ADS. The generated file includes a statement "ADS_SPC_IF" which is said "not defined" in ADS.

How can I solve this?

Can I import it into a net file, other than a schematic file, and then modify it with the syntax elaborated in this page?

Yes, the method I posted previously is an eligible answer to this problem.
