JDBC test step close connection

I am using Soap UI 4.01. I have created a test case with 2 JDBC test steps. I am not using Groovy script to open the connection and run the query. Instead, I am directly using the JDBC test step to create a connection and run the query.

1. How do create just 1 connection for both the 2 jdbc test steps?
2. How do I close the connection at the end?
