"Alexa, continue book in the ____ room." How integrated is Alexa with Audible? Can a bunch of echos or dots be aware of their position in a house? Example scenario, I Audible while working my car in the garage, but sometimes one just has to appease bodily functions, and instead of lugging the echo with grimy hands to the Johnny across the house, I'd rather just tell Alexa to continue playing current book in the \_\_\_\_room.
