This seems like an easy and common requirement.
Cloud.
For any row (epic), I want to see directly in a formula column if the row has certain issuetypes linked to it through the 'implements' linkage (if yes, then return 'yes').
For example, I have an epic which implements an IT-application issuetype.
these linkages are not considered children, so MAX#children or any alternatives won't work. The vast amount of solutions I'm finding online are for JQL queries, like LinkedIssues() but I just can't seem to get that to work in Structure's formula functionality.
