Automatically applying "parent revisions" that are not in working copy

Hi,

Is there a way to setup applying parent revisions automatically without getting a prompt like:

 This diff is against commit b9f2edeed9d3e6cad70db7e58e773e7f7a6cebe8, but
    the commit is nowhere in the working copy. Try to apply it against the
    current working copy state? (6b046276146d3b8acd89f8153a8d9e393375b600)

Could not find a param for arc patch that would do this. Maybe there’s some config that can be put into arcrc or something?
