Connect information between team spaces

I currently have team spaces for general, sales and marketing, app development, and product design. My goal is to create an overview page in the general space that consists of tasks/projects, from the other spaces, to one master table and timeline in the overview page for quick viewing. I’d like to be able to add new projects or tasks to the combined table on the overview page and have those tasks/projects mirror in the correct team space, so any edits are reflected across the space. In addition, I’d like to make a product roadmap which breaks down features by versions and have the features mirror as projects/tasks on the corresponding boards. Is this possible? If so, how?
