I would love the ability too quickly add my entire physical library to Hardcover. However the process of scanning each book then clicking lists then clicking owned is tedious when you think about it for hundreds of books. Having the option set default fields for a series of scans would be amazing. For example, set "want to read" and "owed' then scan the isbn of 50 books in a row. Click save and all 50 entries get created.

I've toyed with CSV and looked at the api but those get tedious with the amount of additional data lookups that have to occur. Having a clean experience within hardcover would be amazing.
