How do I use left mouse for scrolling?

I have a game where I want to have a feature where you click and drag anywhere on the layout on the Y axis and it moves with your mouse pressed down. I have already figured out how to use the scroll wheel and key pressed to achieve the same effect with the use of a hidden player sprite and the "Scroll To" behavior, but I couldn't do the same thing if I want to click and drag.

Could anyone please help?

You can add 2 invisible sprites(top and bottom), on drag object overlaps which sprite, it will scroll up or down.
