When we need to move a task in multiple lists from one list and keep the other list assignments intact, the process I have found to work is to 'Add' to the other list, then 'Remove' from the current list. Otherwise, all currently assigned lists are cleared.
  • Ideally, would like to Move from only one of the assigned lists and leave the other assignments as-is.
  • However, it would be helpful if, when I select Move for a task with multiple lists, I am warned that I will clear all the current lists. When performing a group move it is easy to accidentally Move instead of Add/Remove since Move/Add are the same option on the popup toolbar, 'Move' is the default tab at the top, and the selections for each look the same. When this happens it's a time-consuming process to put our list structure back since it needs to be done on a task-by-task basis. It would also help to separate Move/Add on the toolbar so it's not a two-step process to Add.
