Merge Command Formatting

For MERGE commands there is no way to make the conditional requirements with 'ON' follow the same style as JOIN's ON. I noticed back on 5/17/2017 there was a closed 'Merge command formatting options' through the User Voice, stating that an experimental feature was available for SQL Prompt 7.4. What happened? In my 10.1.7.15015, within the formatting styles, there is no area for MERGE like there is for JOIN.
