Name of Custom Garmin GPI

[routeconverter]

I don't know but the first few dozen bytes of the GPI file are:
[..]
where the printing characters are on the right with the non-printing omitted.

I will try editting the file to change My Points to something else.

I guess a small dialog before saving or (which I would prefer)
using the route name as the category name would be a good idea?
