Reminders "whichever comes later"

[augmentedagent]

It would be nice to have the option to select "whichever comes later" in addition to "whichever comes first" on reminders. For example on oil changes, one might put in the date field 6 months from the current date, and in the future miles field 6000 miles from current mileage, but not want to be reminded until the later of the 2 items has happened.
