Use the Cable Attributes and Presets tab in the Personalization dialog to define custom attribute placeholders to be added to the Cables in your projects, and to use the Cable Preset Editor.
To create an Attribute placeholder that will be added to every Cable in your projects, click in the list of Cable Attributes and type a new name for the Attribute.
Note: each Attribute name must be placed on a new line.
See Cable Preset Editor for details of the Cable Presets group in this dialog.
