Group Copy copies primitive, point, and edge groups between two pieces of geometry based on their primitive, point, and edge indices.
New destination groups are created with the same names as their source group counterparts. The names can have an optional prefix. If a group in the destination selection shares the same name as the proposed name then a number of methods are available to resolve the conflict. The transfer process can be skipped for that particular group in conflict, the existing group can be overwritten, or a numerical suffix can be appended to the name of the new destination group. The suffix starts at 2 and increments by 1 until a unique name is found.

Copy Empty Groups
Determines if empty groups should be created. If a group has no corresponding primitives, points, or edges, it will be empty. If this is not chosen, the group will be suppressed. This can be useful to limit the number of active groups when extracting a piece of an object. However, if one has a dynamic group one is using later in the network, and that dynamic group may occasionally be empty, it is important to have Copy Empty Groups turned on or the later SOPs will be broken.
