Problems with sequential convoys

Hi everyone, i'm having issues with sequential convoys.

In my orchestration, I have 2 recieve ports, one after another. The first is a one-way port, the second is a request/response port.
The inital message will arrive via the FILE adaptor, the R/R messages will arrive over WCF (SOAP). Therefore I cannot use the same logical port, they need to be different. I seem to be stuck with the compile time error "in a sequential convoy the ports must be identical".

How can i solve this problem? I know will all certainty that a race condition cannot start. The SOAP messages can only arrive once the BAM database has been updated due to the arrival of the inital message. With this in mind, is there a way of telling BZT to stop thinking this a sequential convoy and just compile anyway?

Thanks for any help guys,
TM
