Add a third grouping to matrix reports

[#1]

Currently, it looks like we can only have 2 groupings.

[#2]

Agree. That would be helpful.

I also noticed that if we want to use status values across, the statuses are ordered alphabetically based on, I think, their 3 letter code. We added numbers to them to see if that would allow us to see them in order but that didn't work. :(

[#3]

Would love five, but I'll take what I can get!

In text mode you can add a third grouping.

[#5]

Yes, being able to add a 3rd grouping on a matrix report would be very helpful for us.
