title: Is there any way to avoid evaluation of new subscriptions over existing entities?
body: <p>When I append a new subscription in ORION, it automatically evaluates the condition and it invoques the designed end-point for that. I want that the new subscription affects only entities appended later.</p>
  
  <p>Is there any way to avoid it or I have to control this at end-point level?</p>
  
  <p>Related to this, is there any batch option to create several subscriptions at same time for a initial load of the platform?</p>
