Thank you for your suggestion.
In general - I think its a very good idea, and one we have explored before.
There are a couple of technical challenges, and a couple of business challenges to make this work.
Technical:
> merging in data from different sources without creating duplication, and successfully recognizing object identity (which things that are named differently really refer to the same thing - like "DR SMITH" and "Dr. Samuel Smith".
I'm very interested in this problem and have made progress towards solving it, but its not working well enough to build a major feature on yet.
Business:
> Most places I've seen that allow 'viewing an EOB' dont let you download the EDI, but instead you download a PDF report generated from that EDI. That PDF report is not as easily parsed.
