Also, what would be the process of returning a "mapped" output of properties for a given stack? I.e. if I'm wanting to have an APIM instance in 2 regions, and then reference the API in a specific region from another project/stack. I wanted to do something like

Output.Create(new Dictionary<string, ApiManagementService>() { { "uksouth", apim }}.ToImmutableDictionary());
