Parent-Child hierarchy feature for campaigns

@Shay My main goal with this functionality would be to group all similarly sourced campaigns together so I can roll them up and understand how my spend & ROI for tradeshows compares to paid search, paid social, etc. I want easy dashboards to understand this for BOTH online and offline sources in a single report.
Similarly to another post, I would like to group individual campaign tactics together under a parent campaign. For example, I may be doing paid social, paid ads, content syndication and a blog all related to a specific theme or piece of content. Today I create a seperate campaign for each tactic. For all offline sources I get from 3rd party sites or tradeshows & events, I manually enter the email address through a HubSpot form, one at a time, so I can capture the proper campaign attribution for a net new / first contact.
My last comment is general in nature. All of this campaign functionality that has been discussed here and on other posts has been core MAP functionality for years. HubSpot started as a marketing hub, and while it has ventured into many other hubs, it has not kept up with the competition in core marketing functionality. I would expect the new campaigns app to be accessible to professional and enterprise levels. Many of us have been patiently waiting for years for campaigns to get fixed and brought to parity with the industry. I hope HubSpot makes all campaign updates widely available and in 2020.
