how to parameterize WSDLs in soap UI pro

Hi,

I am new to soap UI pro and i want to parmeterize my WSDLs. like C:\soapui\INT-WCS-WFT\INT-WCS-WFT.wsdl.

I want this to C:\soapui\INT-WCS-{$Server}\INT-WCS-{$Server}.wsdl.

Server would be - WFT, WFN, WFD etc.

Please suggest. Any help would be higly appreciated.

thanks and Regards,
