I have a spreadsheet of incidents, and am trying to perform trends on this.
The spreadsheet has Incident Details with dates raised.

I want to do a deliquency report which shows incidents overdue by teams,
based on dates, ie 0-10 days overdue, 11-30 days etc.

The sheet has a couple of thousand records, and I do not really want to
manually group all these, so that I can then do a Pivot based on this.
