Bert makes good points.
I could envision a set-up where you click a button for the AmazingMeds database, and you click another button to switch to your CustomMeds database, just like you do to sort out "active patients" vs. "all patients" in your demographic screen.
If you could do this, you might be able to click on AmazingMeds, find a med you love, edit the entry (correct a misspelling for example), and save it to your CustomMeds database. Over time, your CustomMeds database has been populated and you only go to the big database when a new med comes out, or you want to check if a certain dose or form of a drug is available.
AmazingMeds would get updated and overwritten. CustomMeds would be proprietary to you, but could also be copied and shared with another Amazing Charts user.
