ArcGIS assumes a not nullable number field from another database is ObjectID and ignores it

I'm using an OLE DB connection to connect to another database (SQL Server) that has nothing to do with ArcGIS. The tables there all have a numeric key field that is not nullable. When I try to use ArcGIS Desktop (10.2.2) to copy the data it just assumes it's an ObjectID field and ignores it. How can I tell a geoprocessing tool that a field is not ObjectID or force it to include it?

Of course, it always just takes rephrasing the question to post on GeoNet to make me think a little differently and figure out a solution. Since I'm doing this in a Python script, I found that if I make a Query Table first and use the "NO_KEY_FIELD" in_key_field_option, it will make a new ObjectID field that doesn't step on the key field that's already there. Then simply continue with Copy Rows (or Append in my case).
