Assign task to child projects while still be able to see it in parent project

I would like to be able to add task from parent project to to a childproject amd and stilk see thosw task at the parent project.
Have a “general” project where i add new tasks, then create some child projects and assign each task to their corresponding child project but still see those taks in the general project. Juat like gitea where you can assign issues to a certain project board but still see all isues in the same place.

Thank you.

So basically, you want to see tasks from parent projects in child projects?
