To add another Siri Shortcut of the same category, go to menu File – Siri. If there is already a Siri shortcut created with the default name, a message will tell you to choose another shortcut name. Click OK and then Record Phrase to change the name of the shortcut.
Either say the new name, or type a new name for the new shortcut. Click OK to add the new shortcut to Siri Shortcuts and click Done to save the shortcut. Alternatively, you can click Remove Shortcut to delete it.
