yet another gmdl route/map creation question

OK, I didnt see this in any of the FAQs, unless I miessed it. :)

I have a question when using gmdl, I know how to download maps.. But I never messed with the driving direction stuff until 0.5 came out.
I followed the driving direction tutorial and created a POI (from Phoenix to Tucson, about 150 miles for a trip I'm taking on Friday) using the Directions tab in gmdl.
Now on google route it made a map..Is there any way to take that map and actually create a map from that screen or do I have to do it on the preview screen? Or am I missing a step? Whenever I do a manual map with the Preview 1x and preview 2x buttons, I can never seem to get the exact area I want.

Also when I create routes, is there a way to do it backwards in map this? Or must I make two separate trips, one for destination and other for return?

Thanks
