Clone groups and rename instead of copy of copy
Add edge band subcategories by cloning the existing group and renaming each entry properly so the catalogue stays clean.
When adding edge band subcategories, clone the existing group rather than duplicating repeatedly.
Create the required sizes (for example two sizes for a finish) and rename each entry properly instead of leaving names like 'copy of copy of'.
Cloning the existing group keeps the catalogue clean and avoids duplicate or ambiguous entries.
