Clone a catalogue group and edit only the depth variants you use
Duplicate a catalogue group so you can edit only the depth variants that actually exist in your list.
To duplicate a catalogue group, use Clone group, select the target, and paste the copied rows.
After cloning, check which depth variants actually exist in the list and edit only those (for example 450, 500 and 550); leave unused variants such as 400 untouched.
Remove the original group afterwards so the list does not get confusing.
