Allow multiple messages in one Campaigns

Problem statement: You are running a campaign that has n different messages but all related to the same campaign. E.g. Product launch (waves of users), Training (different reminders, different audience, same training). 

Proposal: To generate a main campaign, select if this is a multi-message campaign, if so, you only need to enable a “parent” for those child campaigns. So, when you are managing the campaign, you actually see the results of the parent campaign, and not those marked as child. If you click over a parent, you just refresh the page with those with the same parent campaign. So, your current portal could be kind the same. 

Allowing this to be like this will help keep the campaigns clean and meaningful.
