Yeah, I've messed with that a bit, but it's the whole page layout that I'm trying to avoid.  Thinking of the convenience of the single block schedule.

One example is our Athlete of the Week.  I have an HTML block that I put on our homepage every Tuesday morning and then take back down at the end of the day.  

If you could schedule things generally, like this being on Tuesdays, but you could maybe also make it have specific options.

If we are running a contest from the 1st through the 15th, I could make a block that showcases that specifically during those dates and then automatically comes down.
