How to auto Export all function cells (in a Jupyter notebook) into separate files?

Hi. I usually  develop in Jupyter Notebook (first) before I transition to a Pycharm project.

Is there a way to auto-export all functions (within jupyter notebook cells) to separate files with the same name as the function?

Or, perhaps, there is a better/less tedious way to transition notebook code to pycharm. A single python file export  (within Jupyter) doesn't really help me re tediousness...unless there a Pycharm feature that can convert a function to a separate file?

Thanks in advance
