It would be great if there were an action to merge multiple topics into one topic. Because for example for us there were multiple topics created for the same issue but for different languages like a topic "Frage zur Rechnung" and a topic "question for invoice" which are the same thing but once in german and once in english, so one topic would be enough. Or when there are two topics that are very similar and you want to group these together a merge action would also come in handy.
