Update domains based on subtype in AGOL

[JoeHershman]

We use a data model with a strong emphasis on subtype based domains.  For those familiar with the Utility Network know this approach is used a great deal.

When these layers are published to AGOL the definitions of the subtype based domains are loaded to the service and the service definition reflects these.  The problem is, the UI in AGOL does not support editing or viewing these subtype based domains.

My question...does anyone know of a way to modify these domains.  About the only thing I can think of would be to write a tool that does this with the REST API, which is no small undertaking

Thanks

Is it possible for any of you to make a public feature service and share a link with me, I update domains a lot using the Python API, you can see an example I posted here.  Our data does not use subtype and for some reason when I attempted to publish with one it didnt honour it. I have a feeling I can perform similar to the post using templates/subtypes in the JSON.
