There’s not really an easy way to do that because Zammad doesn’t have something like “linked objects” which mirror.
The easiest and dirtiest way you can achieve this is either trigger or core workflow based for every value an trigger or core workflow rule. That’s not really convenient but the fastest approach.
You could also achieve this by using Zammads API to correct / adjust values or even set them during creation. That all depends on the size of your customer base etc.
