Multiple SOAP operations on single endpoint in Trigger

Description

When defining a SOAP Triggered Integration in OIC we need to select a single operation.
For each other operation we need to create a new integration, which thus uses a different endpoint.

A WSDL can describe multiple operations on a single endpoint. OIC only seems to support a single operation on one endpoint.
We would like to be able to have a single SOAP endpoint handling multiple operations.

Basically enabling a single integration to support multiple triggers would be a way to go (just like the 'Pick' on Message activities in BPEL.

Use Case and Business Need

Partners using our current SOAP services are not always able and willing to change their interface whenever we want to move our API's to OIC.
