Hi
Unfortunately we cannot apply scroll settings differently for same object on page for separate section scrolling on page.
You can either use the same page content on page twice and apply scroll so that one which starts initially should be behind any other content or should be out of page area when scrolled, at the same time the same content which is the copy should start scrolling on page, not an exact solution but can be used as workaround.
Thanks,
Sanjit
