Alienware laptop middle mouse button function?

Hi I was wondering if it was possible to enable the middle mouse button action by tapping both left and right buttons under the trackpad? I had this feature in past laptops and am missing it. I know you can customize each button individually to act as a middle mouse button but I want to obtain their individual actions to their default settings: Left click, Right click; while having both of them pressed simultaneously act as the Middle mouse button. Any thoughts on how to enable this? I saw there was a m11x optimization thread on notebook review where people had enabled it but that site has crashed and I cant access it.
