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.
