It would on tivoweb but not in the UI. Only on some screens - the details screen would show all 3 pieces of info whereever you put it.
The problem with the UI is that it truncates the titles so savagely on the Upcoming Episodes screen (then compounds the problem by wasting screen space with massive gaps, am/pm nonsense instead of using the 24hr clock which would be a lot shorter, channel numbers that are irrelevant, etc), that if you decide that the sNNeNN must take priority over the episode title, your only option would be to put it at the start of the title! This means you'd never actually see the episode titles on that screen
It's good information to have but personally I wouldn't say it's more important than the real title, if it's known. IMHO of course.
