Thanks for comments so far! We all seem to be on the same page. I've actually been putting the active problems under ROS (under a heading: PROBLEM LIST), and the remote stuff like past surgeries under the PMH field.
I also considered putting the problem list in the assessment section but finally decided on the earlier sections.
I'm gratified to hear that others have been struggling with this, and also that other EMR systems haven't done any better.
