Looking to consolidate child task custom form field data onto a single custom form and single field.
What I'm trying to do is consolidate the fields on the custom form on the children tasks into a single field (the same field) on the parent task but on a different custom form.
Basically the Deliverable Email 1 and Deliverable Email 2 have a field called segments on them and I need to combine the data from both those deliverables onto a single field in the parent Email task.

So far, I've made it to the point where I can read the data that's on the child tasks, but I'm not really sure how to combine the data without losing it onto the field on the parent task. I was wondering if this would be possible using only the Workfront modules, or would Creating a CSV file in fusion then populating it with the data then pulling that data into the parent task be better? Anyways any help would be appreciated, thank you!
