Hi @NRedditt,
This is currently not possible but the product team is already working on it: https://community.hubspot.com/t5/HubSpot-Ideas/Parent-Child-hierarchy-feature-for-campaigns/idi-p/29234
I also recently talked to one of the product managers who have a few insights and confirmed this.
If you want to follow the updates and keep up the pressure, I’d recommend commenting on the idea and upvoting. The product team evaluates these requests based on their popularity.
You can also help others find the request more easily (and thus drive traction) by accepting my reply as a solution. I’d appreciate it, too.
Have a great day!
