Hey Martin, thank you for your reply!

In a practical sense - I don't want to have all my steps in one notebook. I use notebooks to explore different aspects of the process and some of them create different steps.

for example, one notebook will be dedicated to explore columns, spot outliers and create transformations for specific column values.

another notebook will be for grouping, joining and aggregating data from multiple sources etc...

I might be missing something here, and would love to continue the conversation live, if anyone is interested in helping out.

Thanks in advance,
Gilad
