Request for Scheduling Matrix Accordion Memory

It would be really nice if the Scheduling Matrix page kept track of which accordions I have collapsed and which ones I've left visible, and then defaulted to that view the next time I use it!

I am the Worship Leader, so I schedule the Music, Production, and Pulpit "Teams" for our church. But there are many other Team Leaders scheduling their own teams. I always collapse the accordions of the other teams' roles so I can just focus on the teams I'm responsible for. It's tough to visualize the schedule with the extra 10, 20, or 30 other roles visible. It would save a little bit of time and the necessary attitude adjustment if I didn't have to collapse them every time, sometimes multiple times a day when I'm in planning mode!
