One thing that I have easily trained my FHH to do using OC is to fly to a particular perch in her mews.
For a bridge I use a vocal reinforcement. It was suggested to me to do that rather than using a clicker so that when she is on my glove I still have a free hand (rather than having to always be holding a clicker).
I can't say that teaching your bird to go to a particular perch will help you at all. It certainly wont if your bird isn't free-lofted. But if it is and it is like my bird, the screaming will happen when she sees you approach the mews. My bird knows that she wont get so much as the time of day from me if she isn't on the right perch (and it's not the perch closest to the door). So she does curb her enthusiasm a bit and behave right off.
