MassHunter - Surrogates and Internal Standard recoveries (EPA 1613)

I will be creating a MassHunter method shortly. The method will be used similarly to EPA 1613 (dioxins), in that I will have Natives, Surrogates and Internal Standards. How can I create the method to get Surrogates to act as IS for natives, but have a recovery based on areas vs Internal Standards? Without knowing much about the software I am wondering if custom fields would be the best way - define Surrogates as IS to get the proper concentration results of Natives, but then custom filed a calculation to get the recovery of the areas vs Internal Standards. Thanks
