Dear Wheeler,
if you want to use PANS FW then you cannot modify the way it works, you need to follow the installation guidelines. If this cannot work in your installations, then you may have to design own solution.
I would just go back and check again and see if it is possible to install PANS system in your space. The PANS system is scalable and you can have >16 anchors, you just need to obey the rules.
