Not sure if this is exactly what you mean or not but I had a simillar idea, or rather suggestion for a problem that I had (and still have).

For the record, my "lazy" excuse transformed into "I have a really bad PC and can't afford a new one" since that.
By tags, do you mean the ones in "trade" interface before building, or the "allowed" tags in city planner's desk? I'd really like to see the former since the latter is really clunky and really hard to tell what belongs where. Even though there is a much bigger variety in "allowed" tags. But expanding on either of them would probably require a lot of effort, so, it's unlikely.
Also Enclave theme would be sick but not sure if there's a single plot that fits under it.
