I found a partial solve for being able to add UTMs to some links (it does not solve the system emails), but it requires recreating the trigger event with a webhook and then an API call. 

If you do a GET API call for a topic, the data it returns includes seoCommunityUrl for the topic. 

I’d like to see this added to the Trigger events for topic related Zaps. It’s likely a faster and simpler enhancement that this idea: 

Use cases: Any action that feeds the SEO URL somewhere it might be clicked. My use case is Slack, but it could also be used for adding rows to Google sheets or any of the myriad apps that could facilitate an action. 

Impact: Increased traffic insights via utm. Community Managers could leverage UTMs for many automated functions relating to topics. Combined with UTMs added or automated with marketing emails, and UTMs on links that don’t have the redirect challenge of topics, you could get pretty close to a workable UTM solution. It would leave system emails as the primary “weak spot.”
