I have a custom field called "Percent Done" (single-line text) on my Epic screen that contains a number.
I am trying to figure out if I can use an Automation (lookupIssues?) that will locate all Epics linked to an Initiative, and average the Percent Done fields in those epics, then display that result in a Percent Done field on my Initiative screen.
I am seeing articles from 2020 that says you cannot use lookupIssues with custom fields. Is that still the case? Can someone help me with an automation that will help me determine the Initiative Percent Done field by averaging the numbers in the Percent Done field of my linked Epics? This is Data Center (not Cloud).
