I'm using ArcMap 10.2.1. I have a simple FGDB with a point feature class called "wells" and a table called "owners". There is a one to many relationship between a well and its owners. I'm curious if there's a way in the Attributes editing window to relate a well to an existing owner record. There's a way to add a new related record, shown below. But there's not a way to relate a well to an existing owner. The only way I know is to accomplish this is to open the "owners" table and edit the "well_oid" field (also shown below). Does anyone know of another way to accomplish this in ArcMap?
