Ingest Preset for Media Encoder doesn't reflect changes to Encoding Preset

Minor quibble but posting in case anyone else runs into this...

For my proxy workflow I created both an Ingest Preset and an Encoding Preset inside Media Encoder. My Ingest Preset references my Encoding Preset (in the 'Transcode files to Destination' portion of my Ingest Preset). I then export the Ingest Preset to an .epr file, which I add to Premiere via the "Add Ingest Preset" button in the Project Settings -> Ingest Settings dialog.

Everything works as it should.

However, if I then change the parameters of my custom Encoding Preset and re-export the Ingest Preset which references it, the exported .epr doesn't reflect the changes to my Encoding Preset. To make that happen, I have to go into my Ingest Preset, change the referenced Encoding Preset to some other preset, then back to my custom Encoding Preset (or alternately, uncheck the Transcode files to Destination' box and then re-check it), after which the Ingest Preset will then reflect the changes to my custom Encoding Preset.
