DRAG TASKS BETWEEN TO-DOS FROM 2 TEAMSPACES

It would be nice if I could interchange tasks between 2 or more Teamspaces - to move from one to another.
Lets say I have a general to-do list/tasks on Teamspace#1, and then I create a Teamspace#2 or more in order to subdivide the #1. Right now, If I want a task to move a task from a task list in #1 to #2 I need to manually registrate it, and it is kinda painfull, when I could just drag it there directly from #1 to #2.
I hope It made sense ;)
