[BizTalk ]Sequential and Parallel Convoy together

Question

Hi Team,

I have an requirement to design Biztalk integration, Appreciate your inputs in designing the orchestration.

1. Receive Start Trigger files - Start Orchestration
2. Data files (Multiple files to be received by Biztalk one after other)
   • Send to Different system and wait for response - send each response to shared file location
3. Receive End Trigger files (End trigger file will be received after all the responses are received by bizTalk for #2) - Stop Orchestration

Start Trigger , End Trigger and data files shares 1 common field and can be used for correlation.
Please advise the design approach.
