The 'Close Button'

I wasn't sure where to ask this question so it ended up here.

Is it possible to have a 'close' button at the bottom of the story page as well as at the top? I'm starting to wear out my fingers scrolling back up on my iPad.

On an iPad you can scroll to the top of a document just by taping the top line with the time.
