Referencing designs/artboards from one Figma file to another

Give Figma the ability to display an artboard(s) of one Figma file to another Figma file. So, rather than copying and pasting between two files (detaching it from its source of truth), the designer can “insert/link” the artboard to be displayed on another Figma file. Then, if the inserted artboard is updated, it will also update in the file where it is inserted (or any other instances). Very much like components work today but w/out the need to turn the entire artboard into a component.
