How do you insert values into custom fields into the Mosaic Dataset table?

[المشرف العام]

I have a mosaic dataset (file geodatabase) with an additional field added to it (id that is integer) and I'm trying to accomplish in ArcPy what I can do manually--which is:

1. Add a new raster (single tif file) to the mosaic dataset in the file geodatabase.
2. Set the additional field to a value.

I've successfully added a raster using arcpy.AddRastersToMosaicDataset_management, but I don't see how I can set that additional field.

If AddRastersToMosaicDataset_management returned objectids, I could manually set it via an update cursor but I don't see how to get that value.

Is it possible from ArcPy to update a custom field on a Mosaic Dataset?
