XB7 Firmware Updates / Days & Times? Changeable?

Is there a way to specify the days/times that the modem will take and do an automatic update.

There are times when the internet is being used (for streaming for example) and an update caused a full halt and questions from the viewers when the stream was back.

It would be nice to say to the modem, for example, "hey don't update on a Friday and Saturday, between the hours of 7.30pm ET and 4.00am ET, any other time, do as you wish"
