Pinpoint Campaign Serializability

Given this scenario of scheduling 2 campaigns for the same endpoint, when the Campaign#1 notification is sent, is there a way to retain the original data of zipcode=1111-1111 that was set when Campaign#1 was created? My understanding is it will always use the latest update of the target enpoint. Is there a work around for this?

• Run Data Import Job, Create Campaign#1　EndpointID: XYZ

      endpoint.zipcode = 1111-1111
      Set the schedule of the Campaign#1 to be sent weekly Friday 7PM
  

• Run Data Import Job, Create Campaign#2: EndpointID: XYZ

      endpoint.zipcode = 2222-2222 (updated)
      Create and run the Campaign#2 to be sent on Friday 5PM (earlier by 2 hours from Campaign#1)
