Well, you could try going around that. My suggestion is maybe to put like a number on each route, town, etc. Then post a thread for the map, put down what the labels mean and presto.
For instance, consider this simple map.
1------------------2

1. Nuvema Town
2. Flocessy Town
3. Route 19 (Gah, it's supposed to be in the middle of the dashed lines, but you get the idea.)
