Yes. When you create and save a barcode in vector EPS format, that EPS file can then be re-opened in Barcode Producer's editor with the File > Open EPS Barcode... menu option. This lets you treat a saved barcode as a template for future barcodes.
This is particularly helpful if you want all your barcodes to look the same, except for a change to the value.
Pro Tip: If you open your vector EPS barcode in a raw text editor like BBEditTextEdit, the settings used to create it appear in a PostScript comment at the top.
