We need a way to know where to send a sim to class

Every once in a while I'm having a sim not get their "head to class one hour early" interaction, and then I'm stuck with my sim needing to be there within an hour. But if you click on the buildings, they give no indication even moments before which one is the one they have a class in, so I keep just sending them in a general area nearby and hope for the best. And why wasn't it just set up so they simply go to class one hour before (along with a send to class button at that time instead of when they are already late) and into the building early like regular school or work, instead of this silly two step process where they go stand outside like idiots? Same thing with scouting and such; they should go early or they miss half of it. Just one more thing to fail. If they're late they lose grades big time, and if you have multiple sims it can be pretty bewildering, especially at Foxbury where everything looks the same (as a modern school does).
