I am not sure you design is even feasible. As you know there are unlimited number of shipping conditions. How can they integrate with MOT in APO. APO MOT is basically used to determine duration. There may be numerous shipping conditions with same duration: USPS next day air, UPS next day air, FEDEX next day air, etc.. Why would APO need to have this level of informationn?
You can always customize this intergration but based upon your rules.
