On an Organization, we have a Detail called "Region". The goal here is to filter queues using that Region.

As far as I can see, Organization Details can't be used in queue filters, so I thought we could write this attribute into a custom field on the issue and then filter that way.
I thought I could achieve this through automation to set the issue region based on the organisation region when an issue is created using:
1. A smart value, but it appears Organization Details aren't included as smart values.
2. Accessing the API using Organization Properties, but it seems that organisation properties are different to the Organization Details I'm trying to extract.
Is there any way to achieve this?
