Is binding devices possible to xFi Gateway or xFi Pod

I already contacted Xfinity and it seems like they weren't understanding what I was trying to tell them. I recently added a xFi pod to our Gateway system and now my laptop is automatically connecting to the xFi pod which is 20-25 feet away (6-8 walls away) vs. the xFi Gateway which is 4-6 feet away (no walls in between). I simply asked if I can bind devices manually to either the Gateway or Pod and at first they said yes but could not point me into the right direction. Then they were telling me to disconnect from the WiFi on my computer and to connect to the Gateway only not the Pod. I told them I only have 1 access point which is the Gateway and then they were telling me to rename the pod as if it was a Access Point when 1. it's purpose is just to be a WiFi extender and 2. it shares the same SSID as the Gateway since it is a mesh system. I then asked if I could rename the Pod's SSID which seemed impossible and the representative said it was not possible and I also asked if I could just turn the pod into a Access Point to work only via Ethernet but looks like it's not possible. So after about an hour and half of going back and forth I got no answer on how to simply bind devices to either the Gateway or Pod. The issue for me is I am paying for 800mbps and the pod drastically drops it to 150-250mbps. Which I understand the pod only supports up to 500mbps but I find that not being able to bind devices through the Xfinity app or Admin Dashboard (10.0.0.1) a bit ridiculous. The representative then told me that a technician must come to my house to fix this issue which I don't think he will be able too although the technician would probably have a better understanding of the issue then the representative. 

I'd really like to know if this is possible if not I feel like I wasted $120 on the pod.
