playlists - total length

Is there a way to request that Apple add back the total time per playlist in itunes??!! All fitness instructors that use itunes have to now manually calculate the time by adding the song length together - what a royal pain. I'm sure that there are others that also miss this feature. We change our lists constantly and now have no idea if we will run over our time per class without adding manually - this creates issues since the gym is scheduled for many classes and we need time to switch out our instructors and students. What a huge FAIL by itunes!
