When sorting a collection's entries by date, the control panel orders them in descending order. The latest entry (by date) is thus displayed at the top.

Example:

2018-12-01-0800.lorem.md (will appear at the bottom)
2018-12-02-0800.ipsum.md (will appear at the top)

That's great when we're displaying blog posts.

In my case however, my entries aren't blog posts, but events. Their filename follows the same pattern, but I'd like to sort them in reverse order (i.e. the first event, aka the oldest in the list should be at the top).

I can't for the life of me find how to do this. Any ideas?

Edit: just to clarify, I'm not talking about how to sort them in the template; I'm strictly talking about the control panel.
