Pre-populate Certain Jira Cloud Fields

[Blake Falanga]

When a new issue is created and an associated Epic is selected, I'm looking to pre-populate some custom fields (based off the same fields in the Epic). Is this a possibility? Does anyone know how to go about this? Thanks!

2. Create the following automation rule:
   
   P.S: In the action, I used the Summary field, but you can select any field(s) you need
