You can get this information.
Open the prescribing screen.
First, you must be sure that every medication on the patient's medication list has a "sig" filled in. If one or more do not, you will get an error message.
At the top left, click "ePrescribing" then "Manage via NewCrop Screens". When that opens, look for the link to "Surescripts Drug history" and click it.
You select the desired interval and you should see the prescription history for all providers (at least with that insurer).
Here is an example of a screenshot of what you get.
