Needing a $PRP Equation for Multi Body Naming/Numbering Each Body

I work for a sheet metal fabricator and we have just purchased new robotics in our shop. The built in Solid Works sheet metal functions are extremely useful and powerful especially when it comes to multi body parts.

The problems I have are when making the drawings for a multi body part:

When multi body parts are placed on a drawing they all have the same part name/number. I am looking for a way to give a unique number to the parts that is consistent from the base part (without using a Macro).

My current approach:

The direction that I am leaning towards is to embed a variable within the cut list properties. So far I have converted my part into a Weldment. From there I have the cut-list table is generated.

Going into the cut-list properties the description is a text value that is defaulted as "Sheet"

What I am looking for:

I am wanting a way to create an equation that will output the Cut-List-Item# as a single integer.

My goal:

I want to have this number embedded into the cut-list so that when I am exporting to my CNC laser or CNC break machines that the same part number automatically appears the same on the drawings as in the part file itself.
