Configure self lookup in new data management

It seems like the new Data Management no longer supports configuration of self lookups. This blocks a use case we have configured for 1 product and would like to also configure for our other products.

Use case

When reporting on usage data (brought in via S3 bucket), we would like to show the parent feature of features (to see (part of) the feature hierarchy). Therefore, the Feature Object contains a field 'parentfeatureid' that should look up to 'id' on the Feature Object itself.
