Flows as components

I’m working across several teams with complex flows, and need a way to inherit the updates to those flows that other teams are making in real-time (screen order, specific screens, flow lines).  So when one of those teams make a lot of small or big changes to their flow, currently I’m having to manually update my files, which is error-prone, time-consuming, and tedious. 

I’m imagining something like a component for an entire artboard as an “page-level” component.  Many layers of nested components - i.e. atomic, molecule, organism, templates, *pages*.   Right now there are a lot of limitations using components for this use case (i.e. connector lines don’t always work, components are cumbersome at that scale, restricted max nesting layers).  Alternatively, we could have an iframe or window that shows the other flows.
