Shortcut to VOC budget method

In the Bird's Eye View info, the "Shortcut to the VOC budget method" caught my attention under the "FAQs for IEQc4.2" section - this applies to me! My assumption is that touch-up paint (for an object with a factory-applied higher VOC finish) - regardless of how little is used - still needs to comply with the VOC standards. To achieve the "shortcut", how should I proceed? Select the "None of coating products exceeds allowed VOC level" option, fill out the VOC table with all the complying products, but then in the Special Circumstances show a budget calculation of how ONE higher VOC coating (not in VOC table) is counterbalanced by another lower VOC coating (already listed in the VOC table)? Thanks!
