Junping -
I think this might be what you're looking for.
From within the DevTest Console of your VSE, you can set the virtual service model behavior by ::
- Right-clicking on the deployed virtual service
- Select "Specify the Model Behavior" option from the contextual menu
- The "Specify Model Behavior" dialog opens. It looks like this ::
You can also create a new recording of the service with the transactions you need and then merge the 2 service images together.
Hopefully this helped,
Jeff
---EDIT---
I should've mentioned that this is using DevTest 8.1
