Retail Barcode Labels

Currently there is an option to "set number of labels to match number of items in stock" however I want to print a certain number per barcode to export and send to suppliers. Currently I have to go through 1-by-1 and input the number 1 for every barcode when this could be a simple toggle "Set all barcodes to print X number"

I have nearly 2000 barcodes so this is time consuming to do it 1-by-1
