Is there any way to easily swap between audiobook and book with Kobo?

I know you can with Kindle but wild horses wouldn't drag me back to Amazon. I love the Kobo experience much more.

I have the Libra Colour and prefer that but while at work my only option is to audiobook so it would be nice to easily flip between the two.

From what I gather its not possible but anyone found a way to make it work?
