cross project tracker references and user management

Hello community,

Is there a way to share users across multiple projects?

We have several projects where trackers are connected via reference fields. However, if a user is not a member of both the source and target projects, they either cannot see the referenced items or encounter errors when editing trackers — even in the project where they do have access.

Ideally, we would like to avoid manually managing the same users across multiple projects. While we understand that not all users should have access to every connected project, it would be acceptable if broader access is required for reference resolution to work properly.

Is there an option or configuration that allows tracker references to function regardless of project membership? I’ve looked through the settings but haven’t found a solution.

Thank you in advance for your help!
