Remote Administration of Circle on Nighthawk Router?

I recently enabled Circle on my Nighthawk router at home, and it is working well.  I am easily able to monitor and configure the parental controls when I'm at home via the app on my phone.  My question is:  Is it possible to perform administrative functions remotely via my phone?  For instance, when I'm at work -- across town -- am I able to change "Off time" for one child or another?  Or can I only make changes like that when I'm at home and within reach of my router?

I couldn't find an answer to that anywhere online, so figured someone here might know.  Thank you for your help.
