Reading the DeLorme Forum, it looks as if I need to rethink how I do things:
" you can only see one saved track at a time on the GPSr (in addition to the current, active track). Draw lines are not routable. On the other hand, you can see many draw layers simultaneously on the GPSr, or you can combine multiple draw lines in a single draw layer. This allows you to do things like mark multiple trails in different colors and see them all at the same time on the unit."
