Hi @jkane
Welcome to eazyBI community!
There is an option on how you can pass down the Epic custom field value to stories and their parent issues, and then analyze stories by this custom field value. It is limited to any Single value dimensions and values only (not the history).
You can use update_from_issue_key as an additional parameter in advanced settings for passing down the custom field value. We suggest creating a new calculated JavaScript custom field to copy the value from the original field, and then use it instead.
Please check out community post an example: Aggregate story points on stories under a epics grouped by a custom attribute
After importing this field as a dimension, use it in reports as any other custom field that has values in all level issues.
Best,
