Support grouping / advanced grouping in the review notes app

We've heard from clients it would be great to have grouping (advanced) options in the review notes app. Sometimes a playlist can contain multiple versions across many sequences and currently all versions are displayed in a long list. Its possible to create multiple playlists for this, but having the option to group versions together and quickly expand / collapse group would make navigation around the review notes app much easier.

This would include the option for advanced grouping (for example, group versions by sequences and then by shot)

Please add your use-cases here and vote up the feature if you'd like to see this implemented. Thanks!
