Multiple printers in Configuration Profile for com.apple.mcxprinting?

I am using the JSON template for com.apple.mcxprinting (https://github.com/Jamf-Custom-Profile-Schemas/ProfileManifestsMirror/blob/main/manifests/ManifestsApple/com.apple.mcxprinting.json) which works well but I can't figure out how to get more than one printer in the User Printer List.  If I work with the profile in Profile Creator or iMazing Profile editor, neither is able to specify more than one printer either.
Apple's Dev. Docs show an example profile in XML and looks like just a Dictionary with a string identifier and a dictionary of print attributes (printer URI, PPDURL, Name etc). See: https://developer.apple.com/documentation/devicemanagement/printing
Does anyone have an example in JSON or XML that is working with multiple printers they can share?
Thanks!
