FR - 2 & 3 set of Checkbox Expression Controls

We currently have 1 Checkbox but a set of 2 in a row and up to 3 in a row will be good towards making the EGP look more professional and less like an overgrowth. The EGP gets unwiedly tall in PPro. We'll also be able to set up more logical and user-friendly sections/UI within the EGP.
