Sonarr v3: Indexer used to Download Episode?

In Sonarr v3, is it possible to enable an Indexer column under:

  • Activity > History > Table Options > Indexer

It seems like the Indexer only are displayed for Grabbed episode.

I would very much like to see which Indexers are used to Download (Import) episode.

That would give me an overview over which Indexer that are used and therefore are relevant to keep Donate to.

No Indexer displayed for Downloaded Episode:
