Changing PAN ID of tags while moving along different networks

Hi,
I want to deploy DWM1001C module for forklift tracking in a warehouse. As limit of anchors under one initiator is 30 as of PANS firmware 2. I gone through the scaling limits i.e, need to maintain sufficient distance between two anchors.
But i want to divide the warehouse in different zones having anchors of different PAN ID and wants tag to switch PAN ID as it switches different networks.
I want tag to switch PAN ID after listening Beacons from anchors.
Please help me how i can achieve this functionality in tag . Where it stored the PAN ID of anchor after listening Beacons from anchors.
Thanks
Akansha
