Need help parking my w203 on a snowy hill

I've been driving my w203 with a 6-speed sequentronic automatic for a while and because of my activities I need to park it on a semi-steep hill which is slippery because of the snow. When I press down the footbrake, it simply starts sliding down with rear wheels locked. There is no parking gear (P) on the gearbox so I cannot find a solution. Has anyone figured out anything for a fix?
