How to have Zotero automatically fill in missing metadata from the DOI?

I have a large number of article entries in my library, whose metadata is only partially filled in. In particular, the year entry is missing.

All of these entries have a valid DOI, which I can use for example to use the "add items by identifier" feature. If I do that, a new entry is correctly created with the "year" field correctly filled in.
Unfortunately, this also creates an additional entry instead of amending the already existing one, and using the merge duplicates feature then creates a new entry which *does not* include the year field.

Is there a way to select a bunch of entries and have the metadata be automatically refreshed from the DOI?
