Most of the times, it becomes a hassle when dealing with Revit's annotation leader and controlling the elbow point. Sometimes, it is just enough to have no elbow or sometimes it may require multiple elbows for the leaders, depending on the needs of positioning the text on the sheet. Obviously, it is not about removing the leader line through properties palette, which will entirely remove the leader line.
I have searched everywhere, and I'm unable to find a workaround for the same. If there's any suggestion, please let me know. Or, if you think this is a need as a feature, please up vote!
