I'm not sure that he has the option. I'm not a licensed prescriber, but it still lets me do it(and puts my name on it). I would rather that it didn't let me in the first place. So, maybe it is a bug in that it shouldn't let non-licensed prescribers prescribe medications. Let's our MA do it also.
rather than a bug, it would be better to be able to forward it to the licensed prescriber, as occurs with the encounter. I would also like to see this for letters, addendums, orders, requisistions, as well as scripts.
There is too many places where the prescriber/practitioner needs to enter all the info in order for it to show the proper signature.
