Allow fields available in the CTO to be used in General Electronic Services (GES)
Fields found in the CTO should be available to use in url templates and service availability rules within General Electronic Services (GES).
We use some GES's to link out to our resource sharing system that uses OpenUrl parameters in the url template. We've discovered that many books only have editors and don't include that information in the general author attributes within the CTO. Instead, the editor gets added to rft.sau in the CTO and it is the only field in the record that contains editor information. If you add this field to the url template in the GES and you get an error (error message = "The URL Template you entered contains invalid parameters: rft.sau").
I submitted a support case through Alma, which got transferred to the Primo team, and was closed with a comment about Alma not being designed to do this and to submit an idea exchange.
Here are some examples where any author related information is only available in the rft.sau field.
Finally, because these are not local records, there is no workaround to add the editor field to other fields and get used within other existing and working openurl fields.

This would be extremely helpful to getting complete citations out of Primo and into ILLiad!
