Generally if the Vendor doesn't supply the data you would have to try and look it up in another Table.

By the way you could have used ASIM for this (simple example):

// or use _ASim_NetworkSession if you dont need a parameter
| where Activity =~"Threat"
| distinct DstGeoCountry, SrcGeoCountry

note: GeoCountry are optional in the schema
| parse kind=regex flags=U AdditionalExtensions with * "DstLocation=" DestinationCountry ';' * "SrcLocation=" SourceCountry : string
this is correct line.
