How do I have dynamic content in ad writer that points to each vehicle's specifice?

Just like in the stickers, there are options to add vehicle.make, vehicle.model, or dealer.address, etc. to use these you will need to create a custom ad writer comment. Settings-> Adwriter-> create a comment title-> Save-> then click on description box-> Type the @ symbol for access to dynamic content.-> save again. So it's title first to save, then description 2nd is the comment that will be applied.
