The case is that for some groups the customer can have up to 9 plus users associated to a group but in the template, it is only planned for up to 5 children

here's one that I updated that takes up to 14 users/groups. I tried extending it out for beyond that but the excel formula stopped recognizing my cell references, so we had to add those into the system manually.

I ended up just updating the XML (copy and paste for the extra children needed and amending) accordingly before loading into the app which also worked with as many users as needed.
