himilecyclist - you might also want to take a look at this macro. It also gives you the option of using GGZ or GSK.
As with GSAK it allows exporting Child Waypoints as POIs, however it does it in a slightly different way which you might like to try. I have used it with a Colorado, Oregon 300, Oregon 450 and, now, and Oregon 600 and it works splendidly! (Well, I would say that because I wrote it...
)
(On the whole, POIs behave much better on the Garmin units than Waypoints for this kind of static data. They are unlimited in number and much easier to manage remotely. Waypoints are for data that you want to be able to edit live on the unit.)
