Uhhh... page65.2/PoA already works like this, if you go to the pulldown (in Interactive) and select from your list of preparers, OR if you go to the correct input code (1, 21, 41, I believe they are) in Batch.
EXCEPT for Preparer #4, which I believe DOES work in Interactive, and continues NOT to work in Batch (you must input each code individually). At this point I have lost track of what year I started raising it as an issue, but the Ctrl+L(email module) inside of Lacerte still worked for conversing with them.
