Feature Request: Multi-Measure Processing for MeasureService

[Capt-Mac]

$evaluate-measure operation currently fulfills the requirement of evaluating a single measure for a chosen subject population, however when a user requires the same subject population to be evaluated against several measures, it requires subsequent requests and redundant data layer calls.

This is especially useful for any users that are performing quality reporting for a specific population over several measures and can now handle in a single request.

I have also logged this with a standards change request:
