MRA is not Great at handling POI's. The Balcony roads list above opens fine in Basecamp as waypoints. To use the list in MRA it can be uploaded as a POI file. In MRA this has to be attached to a route (but not included) and is visible only a certain zoom levels. Its one of the limits of MRA POI handling. If you have an MRA account, basecamp or Google my Maps you can see the location of the waypoints in the file.
I dont use MRA a great deal so was unaware of its limitations hence the suggestion of someone more knowledgable to do it, if it cant be done so be it, but it will work in mapsource or basecamp or google maps for those who wish to use it.
