Hi Brandon, There are no native Master Projects (or Sub Projects, depending your point of view) within Workfront, but over the years, several widely adopted techniques have emerged (some Project based, others Program based, etc.) I thought I'd seen an official webinar or LEAP presentation on the topic, but don't seem to have any reference to one, so I might be mistaken. My colleague @Tyler Bushman at Workfront did put together a very informative ad-hoc presentation, but I hesitate to share it as I'm not certain he intended it for wider use. As a fallback, if no one can direct you to an official version, perhaps you could ask Tyler permission to it, or ideally, a "cleansed" version. Regards, Doug Doug Den Hoed - AtAppStore Got Skills? Lend a hand!
