Adding a new flag to a specific gerrit project?

Hello, As part of the effort to improve the documentation of the REST API the documentation team will help us review the patches for the specification. I was wondering if it is possible to add a new flag, like the CR, CI, and V that we currently have. Would be nice to have a "Documentation" flag (or similar) so that the documentation team can +1 that flag. Is this possible? Can this flag be added to the ovirt-engine-api-model project? Can we define a group of users that have permissions to set this flag? Thanks in advance, Juan Hernández -- Dirección Comercial: C/Jose Bardasano Baos, 9, Edif.
