Pipfile not in main project folder

Is there a way to get Pycharm to detect a Pipfile that is in a subfolder? For the life of me I can't figure out how to achieve this.

My project structure is the following:

Project >

    Python code (marked as source root) -> Pipfile located here

    Javascript code

    Various other folders

When I try to create a new Pipenv interpreter the Pipfile cannot be located since it is not in the Project folder.
