SmartThings discover Alexa devices

You are now able to discover the Echo units from Amazon Alexa thanks to @tonesto7 with the release of Echo Speak. There are still some devices that SmartThings doesn’t discover but Alexa does. I’m not talking about Zigbee devices but more cloud - cloud integration. Is there a way to allow SmartThings to discover all the devices on the Alexa units. Then you can pick & choose which devices in return you want SmartThings to add. Alexa discovers all the devices on SmartThings, it would be nice if SmartThings could discover all the devices on Alexa.
