"Nicknames" for tagged objects in multi-page documents OR page-wise objects for easy-viewing

**Is your feature request related to a problem? Please describe.**
When tagging and adding relations between objects in multi-page documents (>50 pages), it is easy to get lost in the long list of objects.

**Describe the solution you'd like**
Nicknames would provide landmarks during navigation of the long objects list in the documents. Alternatively, or in addition to this feature, having the ability to view page-wise objects can help in easing the pain of tagging multi-page documents.
