Notes are we can write into on every page!????

it woud be great to be able for us to write notes into dance pro - especially on the big pages we use all the time at the bottom of the page. like class pages....this helps us track thoughts and issues not only for owners but admins as well.I was just working out average teacher fees per term and would have loved to just jot that down rather that put it somewhere else on my computer or a piece of paper:)
