title: Deploying to Apple Business Manager customers
body: <p>I have a question with regards to the model of publishing to Apple Business Manager (ABM) customers which was covered in part in this <a href="https://stackoverflow.com/questions/54816910/publishing-on-apple-business-manager">thread</a>.  </p>
  
  <p>To sum up, I can publish an app to ABM customers providing I have a list of their Apple IDs.</p>
  
  <p>My question is if I need to know <em>all</em> of their Apple IDs at publish time, or if this list of Apple IDs can be amended in the future without recert?  </p>
  
  <p>I'd like to publish to one business customer's Apple ID, gain a customer, and add that new customer to the list so the new customer gets the app too.  Can I do this?</p>
