Any tools / thoughts for managing two subs in a more coordinated manner

I am the lead mod on r/parkcity (community subreddit for a ski resort mountain town in Utah) and we decided several years back to create r/parkcityvisitors as a complementary sub dedicated to Park City visitor questions.

The reason we did this is that we were finding that high volumes of similar visitor questions (“how is the snow?”) were 1. Really annoying the locals on r/parkcity and making the sub quite negative. 2. were creating a really negative experience for visitors asking totally legitimate questions. We try and keep the visitors sub snark free and super friendly, leaving the main sub for locals to discuss and snark about truly local things :-)

The two sub approach has been a really great success IMHO - both subs have grown well, and in general we believe we have dramatically reduced frustration on visitor questions / improved visitor experience. Totally would make the same decision again. There were other approaches other tourist towns take (like a dedicated weekly visitor mega-post) but our experience is the approach we have is better for the users (and we suspect leads to a lot more “self-service” answers as the visitor subreddit search is way more focused and useful. We know users can filter things by flairs (and we do flair all posts) - but we wanted great default experience without users trying to filter things (e.g. local and don’t want to see visitor questions? - you won’t by default unless you subscribe to the visitor sub)

We have used a combination of automations to try and get visitor posts to the visitor sub the first time, but also automod “capture” potential visitor questions to the main sub, filter them, and manually have the users repost to the visitor sub. That last part is more effort than I’d like but is the only way to do that.

In an ideal world - and I know this isn’t a thing - I’d love to be able to “link” subs in some way that mods could move or “lift and shift” posts between interconnected subs almost as if they were one “group of subs”. But ignoring that fantasy - I’m curious if other subreddits have done something similar / have any techniques or found tools that have helped.
