Hold-able UIButtons inside a Scroll Rect

Hello guys,

1. So basically, I have a scrolling carousel of UI buttons inside a UI Scroll Rect. Working!

2. Next I add a "Hold" functionality using an Event Trigger component with a Pointer Down event to each button. Working!

3. But the problem now is that, the carousel is no longer draggable. It seems the Drag Event for the ScrollRect is absorbed by the buttons' Event Trigger. I am able to scroll by dragging from the spaces between the buttons, but this is not acceptable.

Any ideas? Thank you in advance
