In our Phabricator installation, there is a project A, of which various people (B, C, D) are members. If B commits a revision and flags A for audit (thereby allowing either of C or D to perform the audit), that audit will show up in B's "Needs audit" list, because B is also a member of the project A. This is annoying for B because B cannot do the audit herself, so it's pointless to show this audit in the "Needs audit" list.
When editing the "Needs audit" query, it's possible to filter by revision author, but really what I want here is to filter by the inverse of revision author, so that I can *exclude* the audits for which I am the revision author. As a bonus, the default "Needs Audit" query should have "Not(Current Viewer)" as the default for the "Authors" field.
