Being able to search ONLY OneWorld carriers from a range of starting airports could prove invaluable in the pursuit of lowest costs / maximum tier points.

Are there any tools for maximising Tier Points or does one have to search manually with dummy bookings etc? Sometimes I would be willing to complicate the route in order to get more tier points, although admittedly I generally want to minimise the total journey time.
