Cnmeastro X subscriptions confusion

Is there not a way, to have cambium essentials to take count of all connected devices then generate a total cost for the cnmeastro X subscriptions needed. As I am finding, I have to buy an individual license for each device but not one single online distributor seems to sell those subscriptions for every device. ISP Supplies for instance, is where I buy all of my Cambium products, but they only sell cnmeastro X subscription for one of the WiFI AP’s that I use. there has to be a simpler way, am i missing something.

For customers in the US, we are trialing a Pay-as-you-go scheme. You could freely add and remove devices from your account, and Cambium would simply bill you each month for the devices in your account.

Would you be interested in switching to that mechanism?
