There are several ways to do the alerts.I like to use Extra Poi Editor to download my custom poi files to and build the alert distance into the file.This allows me me to use poiloader in the express mode.Here is the process.

You can download Extra Poi Editor at http://turboccc.wikispaces.com/Extra_POI_Editor and build the distance in for the alert. When you download the program if you get message about OCX file missing scroll down on the main page and under troubleshooting you will find the Extra Poi Editor Installer that you will need to download. Once installation is completed 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 select metric 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 distance 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 in feet you want for the alert. Then click replace all. You now have distance set for each custom poi. Then save as a gpx file. You will lose the built in alert if you save as a csv file. The nice thing about this method is that you can use express mode for poiloader.
