Mike:
I haven't run into a "point and click" method for doing this, however...
Usually what I'll do it put a summary field in the remote parent table that shows the # of children that parent has. This acts as a visual reminder that there's a relationship there. It's less than optimal, but at least there's some way to see those relationship from the parent.
Hope that helps (a little!).

If you go to the Home page and suffix the URL with
?a=ListExternalDependencies
It will tell you the apps which are "dependent" and why, typically due to cross app relationships. That might help.
