4 Terminal PCB Footprint

I have a component (MOSFET) that is a 3 terminal device, in TO-92.  In a surface mount, it's 4 pins (3 pins and a tab).

I'm not sure the best way to deal with this.  On the datasheet, each connection is D, G, S and D(tab).  But on the footprint it's numbered (1, 2, 3, 4).

I have two options.

1) Make the footprint 4 pins (each differently numbered, 1, 2, 3 and 4).  But this requires adding a 4th pin on my component in the schematic capture, which looks strange. Most transistors are only 3 pin devices.

2) Make a footprint that has 3 pins with the center pin large to include the tab area.  But this removes routing options under the componet.

I initially tried 4 pins with numbers 1, 2, 3 and 2 for the tab but got an error becuse two pins had the same number.

What is the best or most appropriate way of handling this?
