Whenever a I change my alexa skill in a way that the utterenaces or schema are modified I have to manually enter to the amazon developer console and change utterances or schema manually in the textbox.
I 've already automated the process of uploading a new version of the .zip containing the aws lambda function and I would really like to be able to automate the update of utterances and schema.
This is a very frequent feedback we do receive from developers, but this is not possible to automate that part, as of today (April 11 2016).
