Best Way to Manage Backup Destinations

Hello,

I've got some jobs configured in SSR. What is the best way to manage the backup destination when the disk becomes full?

When i use the Clean up tool it deletes all the recovery points, not just the old ones. What it should be doing is combining the full and incremental backups to create a new baseline kinda like how the Synthetic Backup works in BE.

Am I missing something?
