Allow adding a "Connect to pop-up window" step from the Step Builder. Currently, there are two ways to add a "Connect to pop-up window" step. One is to record an action that causes the pop-up and allow Test Studio to automatically add the connection step. The other is to copy and paste an existing step. Being able to add the step from the Step Builder prevents having to record a test, wait for Test Studio to connect, and then change the automatically created values to the desired values.
