Just promoting this idea I have voted for: Collaborations - add template document
This is to allow template documents to be selected as a collaboration as well as make a copy for each group to work on. Currently there is no quick way of doing this - for example if you have 30 groups of students and you want each group to collaborate on their own copy of the same collaboration template - you would have to manually go into each group's specific environment, create the collaboration there then add each student individually, which is largely time consuming.
Vote / comment if you agree!
Thanks!
