SOAP Header for WSDL generated in ECC

Hi All,

I have created a custom function module in ECC and exposed it in SOAMANAGER and generated a webservice. The WSDL is fine and can be imported in PI . My only question is - Is there any option to add a header . Below is the screen of SOAMANAGER. Is there any option here so that the WSDL is generated with header and envelope. Any help or inputs appreciated.
