I manage parcel data (ArcMap 10.6) in a parcel fabric that uses the Local Government Information Model. Our parcel data modifications are driven by documents that are recorded at our County Auditor. Each document is tracked with an "Auditor File Number" or AFN.
I would like to add a field to the default Parcel Fabric Plans table that will then populate a parcel attribute for new parcels associated with a plan; namely, a field for the AFN. This attribute would be "inherited" by subdivisons, tax parcels, and lots I create that are associated with a plan. This would work the same way that the default fields Accuracy (has domain with coded values) or LegalDate (none-coded) are entered manually into a plan and then inherited from the plan into each parcel's respective attributes.
I've added a new field to the Plans Table within my Parcel Fabric (shown at bottom) where I would like to input the AFN.

This field exists in my parcel schema. I have added the exact same field name and parameters to my Plans table. But I haven't figured out how or even if I can make this field inheritable from the Plans Table without using a join, script, or the attribute assistant add-in (I'd prefer the solution to be the same as Accuracy or LegalDate inherited value).
Is there a way to accomplish this?
If you've had a similar problem, I'd be happy to hear about any solutions you might have implemented.
