GPX2. Map software

I’ve used the GPX2 software to create a map.  My problem is you can only create one map.  The software will only create one map name.  Has any figured out how to change the names.  I have two areas I ride ATA’s at.  One has over 100 trails and the other about 75.  Currently I load one GPX2 map while the other area is loaded as tracks.  I really want two maps.  I contacted the GPX programmer and sounded like he hasn’t worked on program for a couple years.  Any help would be greatly appreciated.
