Locking inventory items

I usually use the baudbag to manage my inventory, but for playing warrior, with the constant switching between 2h weapon and 1h weapon and shield, the shield always gets lost in my inventory and I have already sold one by mistake.
I am looking for an inventory manager that is able to block items so I cannot sell them. Do you know of any?

Thanks

I only know of AutoShop. It can buyback explicitly noted items: https://github.com/fondlez/autoshop
