See below on how to add a new Installer drop down item which is commonly needed as you add Installers to your dealership:
Open the Administrator program
Go to Tools > Corporate Division Configuration > Drop Down List Setup and locate “Installers”
On the right hand side, hit “New”, fill in the name (under List It), select your corporate division + sales divisions (if applicable) and select "Save"
Don't forget to add as an Employee in the Human Resources module and set up the installers pay rates (see the Employee Manager for additional info on how to complete this step)
