Pycharm Run server error no app.yaml file at '.' for google app engine project -

I am very new in Pycharm and today I have the morning Play Command with the existing Google App Engine Project but without success

I have a very clear error :)

google.appengine.tools.devappserver2.errors.AppConfigNotFoundError: '.'

No Aepkaiamel file because existing project custom file called app_dev.yaml to use it to load general Pycharm server is unable.

How can I change this behavior and tell Pycharm to use app_dev.yaml instead of app.mail? Is this possible?

Thanks
