We have solved this with the assitance of Symantec's backline support. The trick is to create a custom list on the site of your choice with the following fields:
Title, Single Line of Text, Required (will be there by default)
TaskID, Single Line of Text
TrackingID, Single Line of Text
ResponseURL, Hyperlink or Picture
Start Date, Date and Time
Created By, Person or Group (will be there by default)
Modified By, Person or Group (will be there by default)
You need to set the assignment in the Dialog Workflow Component to the list that you created. Then set up the SharePoint properties to point to the site that you created the list in and everything works as advertised. We did make some changes to the SharePoint view after we created it. You can hide (not display) TaskID, TrackingID, and Start Date. Also we changed Title not to link to any item.
