Inserting your own plan

Congratulations on the new look charts and their new options but I am struggling to see how can insert my own plan, I have done this for many years using the write option on the old charts. I simply cut and pasted “my” plan between the departure and arrival airports then could edit out any problems it showed using my flight planning knowledge (I actually enjoyed doing that). The only option I can see at the moment is clicking the “write” icon at the right hand side of the top bar which does indeed get rid of autoroute and shows a simple DCT which can be written over. However for some odd reason it doesn’t allow any “cut and paste” option. I highlight DCT, right click my mouse and absolutely no options appear.
Am I doing something wrong?
