Thanks, Karsten. Related question for you - I'd like to mass delete some lead records. I have the lead record IDs in a CSV and hoping to be able to use some sort of deletion tool; will this be possible?
But the linked solution does not seem to work for lead records. In the prospecting tool there is no way to view and filter all lead records. And in a workflow filter it will not allow the pasting of multiple record IDs as your other solution suggests.
