There are times when you need to filter your inventory in ways that aren't "conventional" and adding icons/tags is a great way to make this happen. You can use these tags to with the shortcodes as well.
The icon that you add here will not show on the website (unless using Flamingo, see section 2)
If you want to add links to the vehicles see, Filtering inventory with icons/tags
Section 1 - adding your tag to VMS
Starting from the VMS overview screen; select Vehicle Inventory
Add Custom Tag
Add Tag to Vehicle
Section 2 - Adding icons in the CarDealerPress plugin (Flamingo Only)
