Possibility to add custom (sub)categories to Properties pane

When adding design properties for widgets, all of them are added to the ‘Design properties’ category in the ‘Properties’ pane of that widget. When adding a lot of them, for example when implementing a corporate design system, this list becomes quite long and a hassle to navigate through.

If you would be able to add (sub)categories to the Properties pane so you can logically group together design properties, similar to how adding categories to building blocks group them together in the building blocks pane, you can organize your design properties and make using them much easier.
