Getting Workshop items to show up in main Workshop area?
I've uploaded some addons for a game (Tales of Maj'Eyal), and the addons appear in my workshop area, but not in the game's main workshop list. Here's my workshop area:

It looks like people can subscribe to them from my workshop area, but it would be more convenient if these addons appeared in the game's main workshop area.

What am I doing wrong, or what step have I not completed, to get my workshop items to appear in the main area?
