Do not automatically delete non-Plesk Route 53 records
When making any update to a DNS zone, all records that were not created/synched with Plesk are automatically deleted. This prevents users from using advanced Route 53 functionality, such as aliases (for CDN, load balancer, etc). Because Plesk does not support AWS aliases (which is fair enough), this specific functionality MUST be configured directly in Route 53. That would only be a minor inconvenience, if Plesk didn't actively delete any record not synched with Plesk on any unrelated DNS update. This means Plesk-managed domains can't really use any advanced AWS functionality or Plesk will take the site offline.
If Plesk simply leaves either non-Plesk synched records alone, or even just those set as a Route 53 alias, this would enable a world of possibilities!
Thank you for your input! We will consider this functionality in upcoming releases if it is popular. Everyone, please continue voting for this feature if you consider it important.
