it is necessary to be able to add an observer in the mass editing of processes

Good day. Now you can see the process only if you - the author - responsible - an observer We also have users who need to add permission to processes that have already been created before and where the user is neither the author nor the responsible nor the observer. Granting permission to the user for all processes is not an option, because users need permission only for the processes of the contacts they have at work. Essentially, a tool is needed so that the user in the "Client Manager" card can see all sub-processes (if he has Jozwill for the stages of those business processes). It is possible? Another option for a partial solution is the ability to add an observer to the selected processes (thousands of processes) in mass process editing... Thanks for the extended answer.
