I require a task to be added to each document when I upload it to multiple groups. Ultimately it would be great to be able to select a different person from each group to complete each of these tasks however at a base requirement, the ability to add the same task description to each uploaded document would be excellent.

As an additional point for the future, having the whole set of document features available when you are previewing a document available when uploading a single document across multiple groups would be a huge advantage.
