Create a new group for a hardware variant in the catalogue
Give a hardware variant its own group when it does not fit an existing one, so you can clone its SKUs into it.
When a hardware variant does not belong to an existing group, create a new group from the hardware screen (Create new group), name it for the variant (for example telescopic draw soft close), and then clone the SKUs into that group.
Existing groups can also be targeted when cloning if the variant belongs there.
