Alexa for Business - "Assignable default skill" and "invoke by Echo button"
Lets let Alexa for Business users assign a single skill which can be invoked via Echo button.
These use cases are:
* Retail for product display information
* Museum Exhibits
* Information Kiosks
* Logistical scenarios where the Alexa device cannot be in physical contact with the end user.
* Especially critical for high noise environments such as where many people are already speaking ie, inside a visitor center location.
The device id already is distinguished inside the setup of AFB and skills can selectively supply information *as appropriate

I have a number of use cases in my mind, where this would make sense.
One show room concept for one of my customers did not make it into production because there was no way to avoid "****" skills and other related stuff.
