bind code to property.

[xxfast]

Hello, everyone.
Suppose you save a part with the ninth 00216-top.
When I create the stubborn material, I would like it to appear only the first part from the name with which I saved the file previously.
In plain words, I would like to bind a property to the code of each part and then call it in separate or in the cart.
Is there a way?

I believe I had solved, putting the description to the rescue and creating a property anywhere with the code.
If there is any more procedure, tell me. .
