Scroll box option idea

I’m not sure if this is even possible, but I figure it never hurts to ask ??

Most of my content pages don’t have comments. But there are a few that have many comments (and I hope that is a continuing trend!) On those pages, if I’ve set the scroll to 60%, the reader would have to page down through a number of comments before the scroll box is triggered.

Is there a way to “fix” the position of the scroll box so it’s relative to the end of the post content – i.e., 60% of the way to the end of the post itself, and not whatever comments and such show up below the post?

Thanks for entertaining the possibility ??
