I'm working with a client who is adding workflow to multiple companies and it's super painful to have to go to every single company and every single workflow one at a time to assign Workflow Managers. What I would love to see is something like the User Access window type of scenario - select a user/group from a list of workflow managers and then mark/unmark the workflows they can manage in one window. (Even if this was something we needed to do "in each company" this would be a big improvement).
