Unfortunately as you know, nobody is responsible for managing August applicants information in citizenship spreadsheet. So I decided to make a new spreadsheet for August, September,... applicants.
I already added all 2019 information (January to August) from original spreadsheet to the new one so if other admins (responsible for other months) like, I can give them edit access and they can update their information in this spreadsheet and in this way we can have a up-to-date spreadsheet for everyone.
New link is:

I also think having a new sheet is required. But I would suggest keeping it to the original format as opposed to adding all the months on one sheet. So it might make sense to just duplicate the sheet so it stays consistent.
