Automatically include item link when duplicating item to different board

In the absense of any coherent and simple way to clone items on multiple boards with the ability to update an item from any board (save for the mirror columns feature which does not solve this issue effectively) we have been automatic the copying of items from one board to another. This serves the base functionality, but the manager of the receiving board is not given any indication of what board the item came from, and has to hunt down the original item to update it. It would be useful to include a link to the original item (or sub-item), perhaps as the first comment in the conversation panel.
