Allow New Project Roles to be implemented globally

When new Groups or Users are created, and they are to be added to project roles across existing projects, this needs to be done manually.

Now because many of our teams implement tasks across projects to specific groups, most groups are a part of most projects in the devlopers role, which allows them to be assigned issues in those certain projects. At the moment, this is an admin nightmare for us as every workgroup we add that needs access to certain projects, we are having to add manually to the developers role. With over 300 projects on our instance, you can understand our pain.

Is there any possible way of implementing, in the future, a way of globally setting new groups up in all or most EXISTING projects?
