aligned section view drop down option

Hi,

I used to be able to create an aligned section view by creating grouped sketch lines across the desired section then select aligned section view from the drawing view menu drop down option (like this guy) SolidWorks Tutorial: Aligned Section View - YouTube 

Can anyone tell me how to do this an alternative way please? I know there is an option to create a aligned section using he section view assistant but i cant make the bespoke aligned views i used to with a simple line sketches. Am using 2016 SP5

Thanks
