E1: 13: Mileage PM's - unique tasks for each mileage

The discussion title is a bit of an odd one and may not correctly describe out situation. We have an Equipment PM situation that wouldn't seem to be that uncommon, but can't seem to find the right configuration and setup to handle it. We have a Fleet where at each designated mileage, a certain list of tasks is to be done. Very similar to how items would be listed in the owners manual of your car.

(One list at 7,500 miles, one at 15,000, one at 30,000, 180,000, 270,000, etc.). These task lists typically include ALMOST all of the items from the previous list plus additional ones (some might be Inspect on the 7,500 mile and "Inspect & Clean" on the 15,000 mile one).
