Pycharm - Code Cells - Using breakpoint

I am using the new feature of PyCharm 2018 called 'Code cells'. Can I place a breakpoint within the cell and have the execution break when I hit that line? I use Ctrl+Enter to run the code cell.

Can you run notebooks in PyCharm?

With Jupyter Notebook integration available in PyCharm , you can easily edit, execute, and debug notebook source code and examine execution outputs including stream data, images, and other media.

Unfortunately, it's impossible to debug editor code cells independently, I created a feature request in PyCharm bug tracker: PY-29672. Please feel free to vote for it.
