What year were paddle shifters an available on the non M 6 series BMW?

What year could could you get a BMW 6 series with paddle shifters without buying the M6? Were they ever available on the non-M series?|||On 5 series, at least, you get paddle shifters if you opted for the sports transmission. It must be the same for 6 series. Also i believe this option became available in 2007 (2008 model year).
