manage C7000 gateway unit remotely with app, please!

Just bought a C7000 modem/router combo. I was expecting to be able to setup remote mangement with the (awesome? knighthawk) app locally, and then be able to manage the router remotley with the app. In chatting with tech support this is not an option on the gateway items (modem/router combos). But she said that this feature could be added to a future firmware update.

My request: please add "remote management enabling" and "remote management" in the knighthawk app for gateway units on your next firmware release! Screen shot below shows what I am missing :(
