After getting a custom scripted field working (see https://answers.atlassian.com/questions/45825747), we want to set that field as the Estimation Statistic on an agile board. However, this scripted field is not available in the Estimation Statistic drop-down list (in the board's config screen). Other custom fields show up in the drop-down list.
Is it possible to use scripted fields in the Estimation Statistic? If not, is there another way (like using a script) to set the value of another field, and use that field as the Estimation Statistic?
