Rem within Jupyter notebook

What may be awesome is if I could have Rem functions within the Jupyter notebook. Each cell in Jupyter could also a REM.

The code block is remnote is static and so I have to run it again elsewhere to remember its function. If REM was part of Jupyter then I could run the code and save them as Rems simultaneously. And I could space repetition my entire Jupyter notebooks directly and run the code again as I test myself on the cards.
This is my wish list. :blush:
