WSDL operation type possible in PI

Hi folks,

Normally a wsdl (webservice) can have multiple action types, for example a particuar service can be used to show distance between 2 points, validate addresses, etc etc,

ideally the wsdl will have in it a wsdl operation type indicating what the consumer of theservice needs out of the service,

But in PI i havn't come across something similar where in the wsdl generates an operation type..

Is it somethng possible in PI?

I don't want to use a field in the schema (Request type) indicating this intent...but instead create a wsdl operation ....
