View more than one object in the preview when adding hooks

I would like the ability to view more than one object at a time in the preview when adding a hook to the flow. Currently when I look at the preview template, it only ever shows one object. If I need to test against multiple objects, I have to do the following...

1. Start the debugger for the connection.
2. Run the flow
3. Copy the data from the debugger
4. paste it into the template so I can work with more than one

This would save me a lot of time.
