python - How to dynamically select template directory to be used in flask?

Question

By default flask uses template files stored in "template" directory :

/flaskapp
    /application.py
    /templates
        /hello.html

Is there any way to dynamically choose template directory according to user logged in? This is how I want the directory structure to be :

/flaskapp
    /application.py
    /templates (default template goes here)
        /hello.html
    /userdata
        /user1
            /template1
                 hello.html
            /template2
                 hello.html
        /user2
            /template1
                 hello.html
            /template2
                 hello.html

Now if I have the username of logged in user and the name of template activated by user, is it possible to dynamically select the directory to load template files? For example,

/userdata/<username>/<activated template name>/

instead of fixed

/templates/

What I am trying to achieve is a wordpress like theme system for my web application where users can upload/select themes for his website.

You can pass the Flask constructor a "template_folder" argument.

Like so...

Flask(__name__, template_folder="wherever")

Here's the documentation: http://flask.pocoo.org/docs/api/
