In the K2 Management part of K2 Workspace, admins can give a user or group rights to multiple processes at once in the "Workflow Server\Users\Process Rights" section. It doesn't appear this functionality is available in the Management site. In a case where a user must be given rights to, say 20 processes, the amount of work required to accomplish this is increased by at least a factor of 10. Since I understand K2 Management in Workspace will eventually be phased out, it would be nice to have this feature added to the Management site.
