In addition to creating a tracked Lead from the Listing Screen, Users can also create tracked Leads from the Vehicle Registry screen.

Click on the '+ icon' in the Grey action menu bar, and the Lead and Test Drive options display, click Lead. 

The New Lead pop-up will display, but unlike creating a lead from the Listing screen, where the Listing is already populated, when creating it from the Vehicle Registry screen it will give you the option of  Selecting  a Listing to add to your Lead.

Select Listing, and you are returned to the New Lead pop-up.  (See Creating A Lead from a Listing for more information)
