Add New Data Groups in RockPlot3D

Use this RockPlot3D tool to add groups to the data listing, for the purpose of organizing the entities in the current view.

Select the RockPlot3D | Edit | Add New Group tool.
The program will insert a new group appropriately titled "New Group" to the top of the data listing.
While the group name is highlighted in edit mode, you can simply type in a name for the group. Or, you can always right-click on the group name and choose Edit Title to type in a new name.
Now you can drag-and-drop any of the available data items into the new group.

Here's an example of how you might re-organize a complicated RockPlot3D view using new data groups.
