Is it possible to use an item context that created in Oracle Pricing, in Blanket Sales Agreements?

 Hello,Do you know if it's possible to use item context that we have created in Oracle Pricing (Oracle Pricing Manager --> Setup --> Attribute Management --> Context and Attributes) in Blanket Agreements?

For example we have created some new attributes in "Context and Attributes" form for context type = "Product Context" and name = "Item" (Item Context).

How can I use those item context attributes in form "Blanket Sales Agreements" (Agreement Lines --> Item Context)?

Thank you
