Is it possible to change the default selections in Accept Revision?

By default Accept Revision ticks all the categories I might down as a reviewer on:

Accept Revision [✓] Accept as sitsofe
                [✓] Accept as Member of Society 
                [✓] Accept as Member of Law Enforcement

Is there a way to ask Phabricator not to check the Accept as Member of Society checkbox by default just for my user (or a set of users) despite being in both projects? Unticking all by default would also be just as good.

(The motivation is that we already know we can’t do “require M of N reviewers” yet but those on enforcement duty have found themselves accidentally being the sole fall person and thus want to increase the likelihood that civvies are able to absorb some of the, um, responsibility of review)
