So I've created multiple SF campaigns (recruitment fairs) that need to be separate for reporting purposes. I've also grouped them under a parent campaign (all recruitment fairs for a particular time period). I'd like to setup a journey in Marketing Cloud that puts all the children of that parent campaign on the journey as I add new campaigns to the parent. In other words, every time a new recruitment fair happens, I'll create the campaign, add the leads into that campaign and then add that campaign to the parent at which time MC should send them on the e-mail journey.
Can't figure out how to make this happen and hooking up Journey Builder to the parent campaign did nothing. Suggestions?
