Service Catalog and Custom Fields

Attempting to create a form with custom fields, however the “Select a Custom Field From Left” area only allows one row of fields. This is of little use as I need to add the following fields in the form. How can I add the following fields to the form?

User Name
Title
Department
Extension
Type of Access
Effective Date

We are running Boss Support Central version 4.0.173.0.

Just completed the update to Boss Support Central version 4.0.183.0 and it appears I can add more than a single line.

Thanks
