How to move the label up or down on the next line in a enumerate/itemize list?

Question

I want to create a custom listing/structured display for some data that is enumerated (in my case a list of FOI requests.

This is a MWE I've already created with enumitem mostly:

The only problem I still have is the “label“, i.e. I want to move that down one line, i.e. it should be shown before the \textsc{An:} as if the first line would not exist. The reason is just that the first line is purely “cosmetic” and should not influence where the bzu. What I've already accomplished is resetting the font to the normal size for that bullet point/list item.

Please make your answer agnostic of whether I use enumerate or itemize or so there, because possibly I'd change that later.

I've also checked the usual spacings, but I can as far as I see I can only move the whole item, not the label/bullet point alone.

But as these are likely the same settings in enumitem or so, I guess that is not hard.

So, how can I move the label/bullet point/number down or up?
