NSCAN entry points issue and a question or two about it

Hi everyone.  I’m playing around with the NSCAN entry point option and I have come across something that I believe will be an issue in the not too distant future.  Here’s the rub.

One of our venues has 2 physical facilities – we'll call them Theatre A and Theatre B.  Theatre A has a main level and a balcony level.  The balcony level is broken into 2 sections - balcony and mezzanine, and these sections are in Tessitura.    Theatre B has one single section as it's tiny.  There are multiple facilities and sections in use in Tessitura for these physical facilities, of course, except for Theatre B which uses a single section.  I’ve been able to identify what sections should be used for Theatre A's balcony and main stage.  The issue arises when we try to break out Theatre B and setup a couple of scanners specific to that physical facility.

For Theatre B they always use the General Admission section .  However, there are times when Theatre A uses the General Admission section as well.  If I setup a scanner for use at the Theatre B entrance and set it to use the General Admission section then it makes sense that someone with a Theatre B ticket could be scanned in at the Theatre A main stage entry point, and vice versa.  Is that correct?  Is there a way to work this out other than creating a whole new section for Theatre B and having Theatre stage managers change all of their upcoming shows to use that new section, as well as making sure the box office knows to use that new section in future shows they create?  Imagine it looking something like this, and with it looking like this I don’t see how it will work:

Theatre B ----------------------------------à General Admission section

Theatre A Main Entrance --------------à General Admission section and other sections as well (orchestra, orchestra left, etc.)

Theatre A Balcony & Mezzanine -----à General Admission section, Balcony section and Mezzanine section

Let me know your thoughts and thanks for your help.
