I'm creating new hardware tokens to drop sink machining into countertops. In addition, I have the placement of these tokens set up to place them in the center of the countertop when there's more than one sink. However, to do calculate this accurately, I'm using the sink width dimension in the formula. 

Right now that value is set as a simple user prompt in the product. I'd like to be able to get that value from the hardware token. What would be the best way to go about this?

Is there any function I could use to calculate the width of the machine token in the hardware token? Or is there a field I could include the width in, inside the hardware token? The only way that seems possible to me is creating a lookup table in the hardware workbook, but I'd prefer another method if possible, to better allow for scalability.
