Confirmation window when running testStep

I saw that soapUI has the API for UI support.

Can I use this UI support to displaying confirmation window after run testStep and before execute next testStep?

lets say i have test Suite:

Test Suite A

------ TestCase 1

------------TestStep 1

------------TestStep 2

------------TestStep 2

When i run TestCase 1, after TestStep 1 finish, I want soapUI to show dialog window and ask user to confirm whether to run TestStep 2 or wait.

can i do this with groovy?

i know in testStep we can add delay between testStep but i can not define the exact amount of delay time.
