Feature Request: Enhanced filtering subscription on mutation that returns list of objects.

Looking at the documentation, it seems like enhanced filtering subscription only supports mutation that returns one object. https://docs.aws.amazon.com/appsync/latest/devguide/aws-appsync-real-time-enhanced-filtering.html

Will there be support for this use case?

Start with the enhanced filtering subscription documentation linked in the issue and examine how it describes mutations returning one object. Define the expected filtering behavior for mutations returning lists of objects, then identify the relevant AppSync implementation or documentation entry point; done should include support for the use case and corresponding documentation or validation.
