Just like labels, collections are available anywhere in the UI to add/remove objects, for bulk editing, and assisting in management.
Steps
1. Go to COLLECTIONS > Manage.
2. Click the My tab.
3. Click a collection to open.
4. Results are a common results (reports) page where you may operate on the items in grid mode.
Example
Go to More actions > Edit.
You may edit any properties of any number of items in the collection at a time.
