Putting notes on a cell

I would like to be able to put notes on specific cells rather than starting a discussion. Like in excel:

Hi Monday guys
I recommend to add notes at columns (head of the column)to put there instructions columns responsable persons , instructions , process, notes
because here is a lot of questions for new people using Monday ,that would facilitate the operation

Thanks

you can add notes only in Status cell. But i hope they will fix that… cause I need also notes in number cell and date cell and so on…
