title: AWS SNS Flexibility to Publish to Subset of Topic's Subscribers?
body: <p>Here is the model I want to build:
  Unlimited topics (I know the AWS limit is currently 3000)
  Unlimited subscribers per topic (AWS SNS documentation does not state a limit)</p>
  
  <p>Each subscriber will have a different schedule that they wish to receive SMS or email messages.</p>
  
  <p>If I have a topic with 10 subscribers where 5 want morning messages and 5 want evening messages.  The schedules can be changed and will be administered by a web app (utilizing the API) by an administrator so building one topic per schedule is not the ideal solution and the variations would chew up a lot of the 3000 topics.</p>
