Auto sort application list by name in the Panel?

We have a Panel, it has multiple application groups, each group has its own pop-up (menu) that shows the running instances. For example, I have a single Kwrite group on my Panel and, when I click on it, it has 28 open files listed in its pop-up. But, they’ve always been in some bizarre order and the order changes (especially during logout/login, but also based on usage) making finding a specific file in the list difficult. You can sorta kludge a specific file to the bottom of the list by closing it and then re-opening it. But when you open/close 50 to 100 files a day, it doesn’t help much. Question: Is there a config somewhere to make the Panel pop-up lists auto sort by name? Thanks, Michael
