Why are there no closed captions for so many lessons?

After completing the first few models, which was mainly introduction and theory, I found out that there are no closed captions available for actual practical lessons like Data Analysis with Excel Pivot Tables, Introduction to Tableau, SQL and many more.
There were CC available for the introduction courses but now when you actually need them, they are not there.

Can you please update the videos with CC? It is not always easy to follow the lessons without them and I especially learn better with CC on.
