On fast-growing teams, it is difficult for all team members to remember & add each person on the team as a reviewer. Our team reviews everyone else's code, so it is very important that every person knows there's a new review going on. Currently the only way to do this is to add each team member as a reviewer (or, with the new 'join a review' option, send an additional email out to the team's email list).

Please add the ability to group certain members into a team and add a 'team' as a reviewer. (This would internally add all the individual members of the team.)
