No, it's not available for TimeChart. There are two options:
1) You can add your own overlay elements and use scroll api call: https://zoomcharts.com/developers/en/time-chart/api-reference/api.html#scroll
2) We can add a new feature to SDK. Priority feature development would cost $250 (it would be ready next week).
