Write an automation rule that triggers automation then runs automation on children.

Joe Mabus_pcyhx5

I want to write an automation rule that triggers automation then looks up children of that issue and runs the same automation on the children of that issue. 

I know I am way out on a limb here, but has anyone done something similar? Dealing with initiatives otherwise I would use script runner and its epic functions, but higher tranches of tickets don't have the same support. 

See the attached image for what I want the automation plan to be.

Hello @Joe Mabus 

This post recommends that you use Advanced Branching with a JQL statement to get the issues (instead of a Lookup Issues action) and then within the branch you can edit the field(s) in the found issues.
