I'd like to add an item with a value to my board, and be able to add other items that are clones of it.
I add an item (the "Original") with the text "+2" to my Miro board
I create a new item that is a Mirror of the "+2" item.
I make a change to the Original item, changing the text to "+3"
The mirror item now reads "+3"
Is there a feature or Miro or app that does this?
