Send value from one entity into and another entity field?

[worldmiros]

I have Account Entity, that has a field called "hourly rate" and Quote Entity that has a field called "unit price". Is it possible to have hourly rate automatically inserted in the unit price when hourly rate data was inserted by the user from a php file or otherwise? I see that in the QuoteItem.php file has an associate array under the function setItemWithData, the key, 'unitPrice'. Is it possible to assign that key to the hourly rate? If so, how?
