manage global template for our cross-office teams
I am working on a global template for our cross-office teams. All projects across four facilities (with three separate regional groups) are created from this template. A project could have 50-1050 tasks. PMs manage by assigning themselves to their tasks. Other departments need to see these in a report to make assignments. We don't want to assign teams as they could vary based on the region the work is being done in and could be in more than one region per project.
Here is an example of a small workflow

How can I:
- manage this workflow so each department can see their tasks and the parent task name (I can't do a custom form for each task as there are so many, but there could be 20 of the same task on a project)
- ensure the correct region sees their work (I can add a simple location custom form if needed)
- If not in a task list like this, pass the work through teams, but manage and report on the duration (both planned and actual)
