Unity UI double Scroll Rect handler?

I have a Clamped Vertical Scroll Rect that has in its Child that it scrolls multiple smaller Clamped Horizontal Scroll Rects. Imagine Spotify or Netflix. Now, unfortunately because of the smaller Scroll Rects, i can't scroll the bigger one.

I have seen this post that has a script https://forum.unity.com/threads/nested-scrollrect.268551/ but unfortunately that script doesn't work for me as the smaller Rects are not a direct Child of the bigger one. Is there a way to fix this or do i have to do it manually (I need it to work for touch screen)?
