You can create free-form text as a definition copy to copy text fragments to other positions in the model.
1. Right-click on the free-form text and on Copy.
2. Right-click on the position in the model where you want to place the copy of the free-form text.
3. Select Paste as/Definition copy.
Now two copies of the free-form text exist. If you edit either of the two texts, the other free-form text will remain unchanged.
