Customizing my Campagnolo 11 downshift - any help?

I am running Campy 11 and I would like to customize the downshift lever so that it only makes one shift down, rather than allowing me to sweep through 3-4 gears.

This video (at 40 seconds in) explains what I want to do: http://www.youtube.com/watch?v=C016ag8aQVo

The reason for this - I almost never need to downshift 3-4 gears. But I often find that when i am in the drops and want to downshift 1 gear, then awkward angle of my thumb means that I'll often accidently downshift 2 gears, which disrupts my cadence and is annoying.

Any mechanics here? Is this relatively easy to do?

Thanks.
