How do you go about getting a global plea to bring all your matters together as one without an attorney

To work out a 'global disposition' where a person has multiple cases in multiple counties, takes getting the prosecutor assigned to each case, in each of the different counties, to talk to each other and work together to coordinate a resolution of all of the cases. That can be an agreement to treat a case in one county a certain way if a case in anotehr county is resoolved in a certain way - that type of thing. It is NOT easy to do - even as an attorney - and would be particularly hard to do as a person representing hiself. But I suppose it is possible to do.
