"for that I need the new table name to be changed in some way"
No, you don't need to change the table name.
Changing the table name would be a slow, more complex, and very inefficient approach.
The neat, simple, and very efficient solution would be to use basic MATLAB indexing and a cell array.
"the row with the note is what I'm trying to do but not sure how."
Use a cell array: https://www.mathworks.com/help/matlab/matlab_prog/access-data-in-a-cell-array.html
As an alternative you could just use one tall array: https://www.mathworks.com/help///matlab/large-files-and-big-data.html
