This looks useful for the purposes of describing areas in detail but setting an event usually doesn't require more than a couple pins to show where it takes place.

I will keep this handy for any future geomapping projects I work on (which sounds like a possibility given that this was interesting to work with)

Overpass turbo is a great tool, but it's not in the same category as a geocoder like nominatim. Overpass is for querying OSM objects, not parsing addresses.
