I have the same question after fooling with the demo.
I guess the answer is to make those comments in the PMH section, but not on the problem list.
It will be some duplication, but there is great benefit in having the problem list entry succinct so it can be searched. Since this information will change little over time, it will require no editing or light editing after the effort of the initial entry.
Let the problem list be the minimum diagnosis + ICD-9 and use the PMH text box for maore of a narrative, expanded description.
