Need Item Subscribers from template to copy to new board/task list

Item subscribers do not currently get moved across when you duplicate a task list or insert a template to a new board. Tasks and updates do, but item subscribers do not. We have a task list of over 30 items that have set Item Subscribers and these do not move across when inserted into a board, meaning we have to manually add item subscribers to 30+ tasks each time we want to use this template. It’s very time ineffective considering everything else in the board is easily duplicated.
