title: pycharm multiple interpreters in same project?
body: <p>I work on a project involving a "scraping" part, and a "web" part.
  I use scrapy framework for the scraping, flask framework for the web.</p>
  
  <p>Is it possible to configure PyCharm within the same project to use 2 interpreters, one 2.7 for the scrapy part and one 3.x for the flask part ?</p>
