[Koha] ‘Replace Record via Z39.50’

[Katharina Klausner]

I'm migrating our library to Koha and sucessfully used marcedit to 
create marc records including item information. However, the marc 
records are pretty simple and I'd like to add more information. I saw 
Koha has the option ‘Replace Record via Z39.50’ from the Edit men u and 
I'd like to know if there's a way to do this for all items at once.

I'd be happy about any suggestions
