HOMEBASE610 review for Retail Barcode Labels

I've had two issues with using this app since loading it to Shopify. One, there doesn't seem to be a way to filter and select just the items that haven't already had barcodes created. And two, if you use a standard printer with sticker tags on sheets- there is no way to select where on the sheet you want to start printing from. These two issues make it much harder to efficiently use the app.
