Overlapping scroll view control.

Hello there! I am currently working with a menu that is quite complex. This menu has a horizontal scroll snap object with a few pages on it. On each page, there is a vertical scroll view, often containing panels and buttons.

(This menu was intended for touch input) I can select buttons fine, and I can scroll up and down a page fine. But I can't seem to scroll the horizontal scroll bar. When I drag my finger, it always selects the scroll rect most closely related to the object you touched, which is always the vertical page scroll. Is there a way so that if the user drags horizontally, it can scroll the horizontal scroll instead of the vertical one?
