In our SFMC instance we have a parent BU and two child BU's mapped to it. I also have data extensions within the child BU's that contain Contact records from our integrated salesforce CRM instance.
Whenever I send an email through email studio or journey builder from one of the child BU's, the contact get's added to the All Subscriber view in the Parent BU and is not available in the All Subscriber view in the child BU. The contact could be a new contact or an existing one but it always shows up in the parent BU.
Is it possible to have these contacts added within the specific child BU from where they have been sent an email from? It's ok if they are added in the Parent BU as well but we need our BU specific users to be able to view them in "All Subscribers".
If this is not supported then will I need to create a new BU specific list and have all contacts published to that list to achieve this view? This seems to be a fairly common use case and I wanted to understand how to best address this.
