Ability to assign a project manager to a project with automated job status/alert notifications

Problem customers are facing:
Equipment/Materials are ordered for a project. The PM has to navigate to the project to find out what was ordered and the status.

Equipment/Materials arrive for a project. The PM needs to be notified as soon as possible so they can coordinate appointments.

PMs are frequently on job sites, access to this information sooner than later is helpful.

Request:
Ability to assign a project manager (ST User) to a specific project.
Allow that user to select the notifications they wish to receive for that specific project (PO issued, PO received, etc)
