I recently read this post, though I’m asking for something different: Delete #mention of entity and recover previous state of Rich Text
It would be nice if there were a way to automate the removal of mentions (or turn them into links) when an entity moves to a certain workflow state. Some members of my team really like to make use of mentions, which is great. Docs are being mentioned in other docs, tasks, and meetings. However, if one of those entities moves to particular state, usually a final state, then that entity shouldn’t appear in the “Referenced” field any more so that this field doesn’t become cluttered and it stays relevant.
