The short answer is to ensure that the PM security group:-
DOES NOT have Project Manager permissions to the "My Organisation" category
DOES have Project Manager permissions to the "My Personal Projects" category.
Assign Project Managers to the Project Manager Security Group
Give the Project Managers Security Group, Project Manager permissions (use
the Project Managers security template) to the "My Personal Projects"
category ONLY.
Permissions are culmative across security groups, so be mindful which groups
your PM's belong to or they may inherit access.
Let me know how you get on.
