Hi,
yes this is possible, see an example at https://www.easy-profile.com/support/custom-sql-where-to-preset-profiles-within-area-city-and-radius.html#reply-7556

Notes:
- "6371" is a constant for Kilometers, is you want to use Miles for your radius then the constant is "3959".
- In the example we assumed Google Map field have alias called "map", so we use fields with name "map_lat" and "map_lng". You need to replace latitude and longitude names with your values, so for example if your field have alias like "address" then you should use "address_lat" and "address_lng"
