I'm currently running Baked Snack 1.0 with Netarchy 3.7.6b. I had the same question about 45 min ago... On my rom, I have "Spare Parts" loaded in my apps section... I opened Spare Parts and in the "Software" section, it has a "Tweaks" tab, click on that and you'll find "Stock App2SD", open that and choose external... I'm not a Dev, I'm just a beginner in this Android OS world... This is what I did to set it up... If I'm wrong, please help all of US out n correct me...
HTH
