Subitems Duplicate and Move

Hello! I have a few projects (items on a board) with a same set of milestones (subitems). It would be great if the subitems could be duplicated from one item to another with a single command. Currently, it is a sequence of commands:

  1. Check all the subitems to be duplicated, click Duplicate. This creates “Item 1 (copy)”, “Item 2 (copy)” …
  2. Select all those new copy subitems, click Move, move them to the other project.
  3. Go into the other project, rename all the subitems to remove the “(copy)” part of the name

Having to delete out “(copy)” from every subitem name is really tedious.
