Dear Michael Arnhem,
Greetings! Thank you for posting in Microsoft Community.
As far as I know, I'm sorry and I'm afraid there is no built-in feature in Project for the web to create 3 different permission levels.
On one hand, I will keep this thread open. Welcome community members and MVPs who have similar experience to share insights and suggestions here.
On the other hand, I understand your concern and completely agree with you, this is indeed a good addition to the current features of Project for the web. Thank you for bringing thing to our attention.
I sincerely recommend sending your valuable feedback to Project Feedback Community. Our Product Team is in-charge of the site and they are constantly checking the comments and feedback from our customers. Many features have been developed and improved based on users' comment.
Appreciate your patience and understanding and thank you for your time and cooperation.
Have a nice day!!
Sincerely,
Tina | Microsoft Community Moderator
