Creating an Emboss on a turned cylindrical part

Hi, i am currently designing an electronic connector which requires an embossed shape or dimple forming into the part to enable correct orientation. The part will be machined on a lathe and then the dimple pressed afterwards into the thin walled section.  I know how big the feature has to be, but am unsure as to how proceed with it's creation.  I tried the wrap feature command, emboss/deboss, but it doesn't deform the inner edge of the cylinder (maybe the command isn't supposed to).  Help!!SolidworksParts And Features
