Is there a way to automatically delete old btrfs snapshots?

Hi guys, is there a way to configure snapper to automatically delete old btrfs snapshots?

Also, another thing, every time I launch the snapper Yast GUI it creates a new snapshot! even if don’t make any change! is this the expected behavior? can it be modified?
Thanks!

snapshots are deleted the policy is set in Yast or from the command line.
