Hi, how do I setup my Pastel Partner inventory to differentiate between NEW and REFURBISHED items.

For e.g I have tires that I purchase from supplier and create serial numbers for each tire.

However if the tire needs to be re threaded then I would send it to the relevant company / supplier and when I receive my re threaded tires I would like them to be marked as refurbished and if the tires have been sent for re threading for e.g max 3x, I would like to discard it.

Not sure if I should use groups or categories to achieve this. Please help.
