Our ISP (Xfinity) is going to start instituting monthly data caps. The Traffic Usage information on the AX6000 only reports on the last few days. Is there a function either within the router or a 3rd party app that can save off the internet usage on a daily bases so that I can keep track of my home internet usage? I am interested in something like this b/c Xfinity is expecting customers to trust their usage calculator.... I'd like to have a tool to back up their results to compare it with something I can create on my own

Thanks!
