I use topo 8 for similar. I export each level of difficulty from GSAK w/its own color. Then I import each of them as a different layer in Topo 8. It's cool to see all the varying types and their locations. If I'm on a straight line run somewhere.... w/just a click...I turn off the harder layers so I can see the easiest finds. Of course that's all dependent on caching w/a Laptop.
