Under admin/structure/panels/settings/panel-page in section Select allowed layouts it's difficult to find out from what category the layouts are. I have created theme specific layouts, but they follow the panel core layout names and if we cannot show the category here I need to add a prefix to every layout just to show this is a layout from theme Foo e.g. Foo Theme: 4 columns 25/25/25/25. I have added the theme name already to the category, but that works only on admin/structure/pages/add/page-foo/next.

Are we able to show the category under admin/structure/panels/settings/panel-page too, please?
