Lemmy Mastadon (automated crossposting?) interaction issue.

I am a mod/curator at [email protected]. We cover tycoon game (Project Highrise, Transport Fever) etc.

I also have a Mastodon account:

https://mstdn.games/@Landgraab_Industries

I typically only post releases or major stuff (not demos, or smaller early access titles) on the Mastodon account. I also add screenshots and tags for visibility/UX.

Today I clicked on the #tycoon hashtag on Mastodon and to my surprise it turns out my posts on [email protected] are being automatically propagated on Mastodon:

When I started [email protected], I was actually considering creating an automated Mastodon account, but it turned out to be more difficult than I anticipated (or I don't know what I am doing).

I am curious how this automated propagation got enabled. It wasn't there a week ago. Is this tied to my mstdn.games Mastodon instance? What's going on here?

I am also not sure I like the current automated propagation method because:

1. It links only to the Lemmy URL, it doesn't include the post URL (e.g. steam/gog page) which is IMO more important.
2. Does not include a screenshot of the game (critical for micro-blogging IMO).
3. Does not include additional tags.

Is there a way to "control" the parameters of this automatic propagation on Mastodon? E.g. by manually adding a "Thumbnail URL" on the Lemmy side, adding an additional post URL and hashtags in the Lemmy body post?

At this point, it almost looks like I am spamming the #tycoon tag. I would much prefer if there was a way to propagate my Lemmy posts on Mastodon using my manual Mastodon template (e.g. https://mstdn.games/@Landgraab_Industries/114221630323024773).
