Please add option on desk community component area under action or somewhere else to modify each topics  permalinks. Currently we can do it for Knowledge Base articles, rather than KB i see its important to community

Even we post something ourselves, to avoid that problem always we have to write short title and post it first for get short permalink and again edit then complete the topic however that's not familiar task for public users so usually we see too much long links and its uncomfortable to see such links shared on third-party websites, forums.
