When doing a "extrude up to surface" to a curved surface such as a circle, cylinder, or sphere, I see no way to select which side of the curved surface you want (picture 1), other than by doing a 2 direction extrude (picture 2), which can be undesirable. This is a problem from a more complex part, where a workaround cannot be used. Attached is the part used to make the pictures.

I am running: SolidWorks 2017, Windows 10, on a laptop, 8GB ram, HD Graphics 530 Graphics card, Intel Core i7-6700HQ CPU.
