move "reply space " just below post when expand

Maybe it 's a detail for most people but it 's quite important to me. i'm a learning community and i propose 150 different trainings . because of this people dont create posts but comment my own posts. this way we dont have stuff all over the place. trainings are all in the same place. I embed these post in my thinkific course. so that they will find them easily. Because they are expanded when embed, the reply button is at the very bottom of the page. i sometimes have more than 120 comments below my posts. it's a lot of scrolling down.. could you please move it jus below the post and not below the comment ?
