Hi! Thanks for posting in the Lucid Community and sharing your feedback about the beta Dynamic Matrix tool. It is intended that you can copy and paste this shape but I was able to reproduce the issue of the ctrl+c/ctrl+v commands failing to create a copy. I believe you've identified a hiccup of the beta experience - thanks so much for taking time to let us know! I've reported this to our development team and will be sure to update this thread with word of a fix as soon as I'm able. 

Please let me know if you have any additional questions!
