As Late As Possible Scheduling

Is there anyway to force P3 to systematically schedule ALAP (as late as possible) without having to use constraints on every task?

For now, I have only been able to do this by forcing the Zero free float constraint on each task. This then forces all tasks to start as late as possible.

The reason why I am doing this is for a pilot project on using Critical Chain in P3. And Critical Chain requires that you schedule ALAP instead of the traditional ASAP.
