Feature request for automatic latest posts: ordering

Hi, I’m using your very nice plugin.

I’m sending daily newsletters based on latest post (automatic latest posts), and it’s working good.
The very latest post of the day is shown on top, the older on bottom.
This is obviously the most natural behaviour in a “read my latest news” point of view.

However, would it be possible to reverse the order? This would be a good option for a news website sending daily reports in chronological order.
Something like an option sort asc versus sort desc in a radio button.
Or older first / newer first, I’m sure you get the point 😉

Thanks,
Kroom
