Hello ! This forum is totally answering to my issue, but I need it on GoogleSheet script format 
Here it's my file : Google Sheets - create and edit spreadsheets online, for free.
Ideally I would like to put comments on the tab "Projects", then still have it if it's relevant when I update the database of the file (if the invoice is still not paid in the next extract, I need to see the old comment). Could you please help me with it ??
Thank you so much !
Split from how to annotate pivot tables?
