Hi Ulrik,
Yes, unfortunately we had to delay this feature until Structure 3.4 to provide better quality. The work is being finalized now.
Regarding granularity: we won't be able to implement finer granularity right away, I'm afraid. From your description it's not even clear, what should define the set of quick transformation for a given user -- does each user configure it for him/herself? If it's a shared configuration, how is "team" figured out by Structure and who has the right to change the team's set of filters? How does that play with different structures? (Most customers have multiple structures.)
With per-structure quick transforms configuration it is much simpler, and the users should get the concept quicker.
There's one trick that you can do to work around this. You can create a separate structure for each team and then use Sub-structure inserter to have each of those structures actually show your main structure. The content will be the same, but the settings, such as quick transformations or preferred views, will be configurable for each team structure.
Hope this helps!
Igor
