There's an artist who delivers their material via DMs, and only makes a post on their fanbox to essentially say "check DMs!".
I know there's a "search DMs" feature, but it seems to somehow catalogue all DMs without the ability to search for DMs from a specific artist, and isn't organized in any way, unless I'm not understanding the layout correctly.

tl:dr; how to find DMs from a specific artist?
