Can anyone advise me on how to make duplicates of whole records I create from start?

For instance if I create an entry:

Bloggs, Joe, ‘Late Medieval Church Architecture in South Loamshire”
Transactions of the Loamshire Natural History and Antiquarian Society
1st series Vol. 12, 1857 pp. 1-15

I need to duplicate the whole record so that I can speedily alter it to:

Smith, John, ‘Early Reformation Church Architecture in North Loamshire”
Transactions of the Loamshire Natural History and Antiquarian Society
2nd series Vol. 16, 1898 pp. 16-32.

I can do this my numismatic software and by cut and paste on a Word document but I as a newcomer to Zotero it seems I can only do so for one part of the record at a time which is very slow and clumsy. Am I missing something or is this impossible?
