Record "Masterpiece" on PBS -- ALL Series

We would like to be able to record "Masterpiece" on PBS every week. 

We know how to use the DVR, and we can set up a recording for any one series ("All Creatures Great and Small", or "Sanditon", for example), but not for every series that "Masterpiece" airs.  I suspect it might be connected to how the show is listed ("Sandition on Masterpiece" will not be the series name for the next show, for example).

We prefer recording over on-demand, for reasons that are not important here.

There does not seem to be a way to set up a scheduled, weekly recording ("Every Sunday from 9:00 to 10:00"), although there is a manual setting that will allow us to do something like that , it does not allow it to be repeated on a weekly schedule.

This should be simple, but it's not.  

Thanks for your help.
