Panel: Make new posts appear on top in panel

I have a very simple blueprint:

        width: 3/3
                label: Projekte
                type: pages
                layout: cardlets
                templates: projekt

Is there a way to make sure that new content appears on the top in the panel?

basically sort from top down.

If your projects have a date and you use num: date in the page blueprint and then sort by that field in desc order, then yes.

If you are sorting by number, this would also work, but disable manual sorting.
