Pause Buffer

I have a Roamio Plus. Is there a way to increase the pause buffer from 30 minutes to something like 2 hours? 30 minutes seems extremely low for a device that can record up to 300 hours of HD content. It seems a simple option in settings would resolve this. i.e. stating times (30 minutes, 1 hour, 2 hours, etc) or percent of available space (10% of free space, 20%, 30%, etc).
