You can download Extra Poi Editor at http://turboccc.wikispaces.com/Extra_POI_Editor and build the alert in.Once you download the program
you will need to set up the preferences you want first.Under options click on preferences.For example using ft for input.Under units you will see editor, select Imperial/US.For Field Read and Field save select Metric.After setting your preferences click on file and click open to select from your computer the file you want to build the alerts for.Then go to edit and click on replace field.Once the next screen comes up use the down arrow for Field name and pick proximity.Under new field value put in the distance you want for the alert.Then click replace all.Then save the gpx file.
