Can I put this in the back of a book cover? I was going to ask a few questions, and then putting the recorder in the back of a shutterfly type book.

Can i replace the current push button switch for a rocker toggle switch?

Can you replace the standard speaker that comes with it with an upgraded speaker?

Can you record multiple sounds and have them play one at a time? Like a different one each time you press the button?
