GEOPAK Corridor Modeler Questions

I am a long-time GEOPAK user, and  I am looking into the new Corridor Modeler approach of roadway design.  I have attended a few Distance Learning classes and I believe I understand the basic workflow, but I have run into several snags.  Can anyone address these from a GEOPAK perspective?

• I sucessfuly imported our ddb file into a xin in order to define styles.  I found our ddb file's naming convention is a litte complicated, so I then found a sample xin somewhere that I would like to borrow heavily from.  How can I edit a xin file from within GEOPAK?  Is this possible, or do I need to edit a ddb and then re-import it into an xin every time?
• I have created a a template for a rural section.  I would like the ability to have a ditch bottom point follow a special ditch profile and follow a particular graphic element for its alignment rather than be at a fixed offset and elevation relative to the centerline.  How do I assign a special ditch profile(s), and how do I search for plan view graphics to define variable offsets?

I know exactly what I need to do in GEOPAK to complete my designs, but I can see the advantage of using a model-based approach offered by Corridor Modeler.

I have trouble justifying spending a lot of money on training on something that I am not even sure we would ever use for production work.

Thanks for any help,
