'Woocomerce Local Pick Up - I want to add a reference on pick up / collection

Hi am using Woocomerce for pre sale of items at an event with a collection only option. When these are collected I want to update the order to Picked Up (or Collected) and ideally send an email but to also and more importantly update the order or record somewhere the reference for the person collecting as it may not always be the purchaser. The individuals collecting will have a unique numbered reference each (a number on a wristband). Ideally I would scan a barcode on the invoice attached to the item for the order and then input the collectors wristband number. Hope this all makes sense! Thanks.
