Managed Chrome Browsers and User Startup Pages

New Contributor II

We've got JAMF Pro and we're a Google Workspace School. In the past we've just used the Google Workspace Admin Console to configure a user's startup pages. I received a request to keep the managed startup pages while also allowing for users to add their own startup pages. What I'm seeing out of the admin console/Chrome (or using a configuration profile from JAMF) is that once the startup pages are managed then the user can't add or remove them. Basically, it's either managed or not managed. Not managed with ability to allow users to change or add.

Anyone have any insight to this? Am I missing something here?
