Family is bad at deleting after watch. Our old Tivo use to do this: when at the Recorded TV menu, where there are multiple shows and it has the name as : The Show Name (3) so there are 3 shows in the "folder". Pressing DELETE would ask Y/N and then get rid of ALL the shows.
The problem I see is what remote key would be mapped to this function? A WMC remote, say the yellow or blue buttons?
