Thanks Doug but I really wanted to know if there is some way to tell Logic the beginning and end tempos and have it put in the information at a certain resolution. I'm aware that this is best done with the flex tool but that's a manual input method and I thought there might be a shortcut.
Not sure what you're trying to do. If, for example, you have a tempo of 100 at bar 9 and want it to gradually increase to 120 at bar 17, the methods I mention work perfectly - in fact, you can shape the ramp, either a straight line or some type of curve.
Adjustable resolution is available as well in both methods based on beats and subdivisions.
