I want to hit 1 button to duplicate & link, because it's sllloooowww to duplicate a feature and link it to it's original when I have to do it to a lot of features.
Thank you for your idea. One way to streamline the process of duplicating multiple features would be to clone the entire release.
At this time, given that option and historical feedback in this area we are unlikely to implement this idea. We hope you can understand.
