Tool to clean up Wikipedia articles where there are duplicate references

mediawikiwikipedia

Sometimes when editing Wikipedia I find an article where references have been duplicated.

Is there a tool that makes it easy to merge all those references to the same url into just one reference?

Here is an example page:
https://en.wikipedia.org/w/index.php?title=David_Green_(social_entrepreneur)&oldid=936659277

You can see in the example that the same schwabfoundation page has multiple references to it.

I went on the wikipedia-en-help IRC and asked.

Someone suggested using Refill as a solution and it worked quite well but is exceptionally slow so I hope to find an alternative.
