I didn't find the option to modify the monomer libraries in my ChemDraw Professional 18.x or higher (part of ChemDraw Professional suite for Windows). How can I get that in the ChemDraw Preferences?

In order to make this function available, you will need to upgrade to ChemOffice Professional (v18.x or higher) suite.

Please note the ChemDraw Professional application included with ChemDraw Professional suite for Windows has limited functionality and features when compared to ChemDraw Professional application included with ChemOffice Professional suite for Windows.
