Consolidate duplicate citations

Hello,

First of all great plugin. An unexpected behaviour: on a longer page sometime I use a reference / citation more than once, literally copying /pasting the same reference to a different part of the page. In such cases I end up with duplicate references on the list.

It would be nice the plugin to detect such instances and consolidate duplicate references into a single entry on the reference list.
Here is an example about what I mean:

References list:
1. John Doe: A scientific paper, 2020
2, 4. Jane Doe: Another good paper, 2018
3. Max Doe: Yet another paper, 1997

In this case, papers 2 and 4 have been consolidated into one entry as they are the same, used twice on the page.

What do you think? Many thanks.
