Can you forward the order or note to the provider? I usually add my supervising MD on all CII's and multiple Rx that I'm personally concerned about (e.g. Lortab/Xanax).
As well, I'd get a Rx pad, have the Rx all ready except for the signature/stamp. After a few weeks, the providers will get used to this and "may* trust you enough to sign a few each day. Now this is trust with a capital T, but, once you demonstrate competence and they should understand you are in CA, your plight is not of your own making.
Feel for you, this does slow matters.
As well, I only have to write Rx for CII's. Does your EMR not e-Rx to Pharmacies? I can't imagine having to write out every script, everyday. Although, duh! in my other "fun" job, I do have to write out each Rx (pain)
