When creating sets of the same type, you may use the cloning function — creating an exact copy of a set. In this case, you need to make only few changes to the properties of previously created sets.
To clone a set:

  • Select the set you want to copy
  • Use the Edit > Clone document main menu item
  • In the cloned set window, make the necessary changes
  • Save the new set using the main menu Document > Save document item or the 
     button on the toolbar.

You cannot copy the contents of one set into the contents of another set.
