Worldmap - UDG with a custom property for location

Hi All,

I have about 80 user defined groups for each of our site locations. I am wondering, is it possible to define a custom property for each group with the address or longitude/latitude and have the world map reference this custom property to place the group on the map?

Does anyone know if this is even possible or how to go about doing so?

Changing the SNMP location string on 5000 individual devices is not an option for me.

Thanks for any help!
