Is your feature request related to a problem? Please describe.
Currently the user has no way to add a price to a Strange weapon that has a specific strange part on it.

Describe the feature you'd like
Just like how you can add a paint to the SKU of a cosmetic to price a cosmetic with the specific paint, there should be a way to add the Strange Part to the SKU of a Strange weapon to allow that specific Strange Part on that weapon to be priced.

An example would be having a Strange Bushwacka (sku=232;11) sell/buy at its normal priced, but have a separate price for a Strange Bushwacka with Critical Kills (sku=232;11;sp33).

Describe alternatives you've considered
The only current alternative is to change the price of your item temporarily and change it back after it sells, which is a pain to keep track of.
