Option to have a vehicle mileage display that doesn't add to the database?
 

In other words, say you would like to have two mileage displays for your signature.....one with all of your tank history and one that just displays current MPG. I know you could just add a text line, but it would be nice if instead you could add a "second vehicle" with the option to "exclude data from database" so as not to corrupt the existing info....and get an overall MPG display and a "last tank" or "last 3 tanks" etc display.

Just an idea.
