Documentation for KeyField of overlay settings?

[ps2goat]

I'm looking at this file.

Is there a way to run a RelativityOne Import job and have some records be Append and others be Overlay? I'm trying to avoid AppendOverlay. The Overlay settings' KeyField from the linked page above seems to mean a field in the load file / datasource could trigger Overlay instead of Append.

Hi @ps2goat ,
Single Import Job can be configured with one overlay mode (Append, Overlay, Append/Overlay).
There is no way for pointing which records will be imported with Append mode and which with Overlay.
In order to import some records with Append and others with Overlay, such import must be divided into two independent import jobs.
