Skylark only keeps a week of news articles

Is there a way to make Skylark keep all news articles? I have had my DreamCatcher plugged in over a month and it only keeps a weeks worth of articles. Is there a way to change that?

I have a 200GB MicroSDXC card in it for this reason.

Here’s an answer from page 21 of my Dreamcatcher Users Manual for storing News articles on an external micro SD card plugged into your Dreamcatcher - -
