I am attempting to add an internal door within a face frame tall cabinet product.  My first thought was to copy the subassembly of the solid door nested within the product.  However, I needed a different style of door (slab for the internal).  I copied a majority of the door prompts and added _Interior to the cabinet carcass in order to add the subassembly to the carcass that way I can utilize the notch value to calculate the door height and width.  After pasting in the sub-assembly and reviewing the the prompts that it would need to work I realize I am lacking a needed area of prompts from the product itself.  I am in need of a solution or alternative method to accomplish the wanted components.  Anyone got some thoughts here?
