I was able to get around this problem by creating a Userform that would appear at the the beginning of the project run with all the fields that would have to be set and an OK and Cancel button. Once the user enters in the variables, they click OK and the values are saved as ProjectSuite variables for the duration of the test run. I even went a little bit farther and setup field validation and a networked lookup that will login to a database environment and let them select a database to test on.
By default, the Userforms don't show when you create a new project, you have to right-click on the 'Advanced' folder in your project and add 'Userforms'. It will appear along with the default 'Scripts' and 'Events'.
