Let me first describe my requirement:
I have a parent issue. (PI-1) I already have a custom process which creates a bunch of children tasks linked to PI-1. (CI-1, CI-2, etc).
These children tasks have standardized summary fields. (Do this, Do that, etc)
When a user searches for his/her tasks, they currently just see a long list of "Do this" tasks. I want to have a custom field on the child issues which is synched with the Summary field on the Parent issue, so that when they filter for their issues, they see: "CI-1 | Do This | Parent Task Summary | etc"
