I have a WooCommerce store where I sell meat. I would like to price it based on the pound, but the cuts of meat I sell only come in specific sizes. For example a pack of proscuitto comes in increments of 8 lbs. Would it be possible to price it in a way that the options for my customers would be only 8 lbs, 16 lbs, 24 lbs, etc. ? I tried using the "Group of" option under the product level, but it didn't work.
