Profiles

Has anyone found it difficult to store a profile in SS4 which has back to back vertical curves that fall on the same point? For some reason I can't create a profile using the end of a vertical curve as the beginning of the next vertical curve. I know there will be a training tomorrow on using the tools. However, I found myself creating the profile in SS2 since its much easier. But now I can't import the created profile onto the SS4 alignment. If anyone has any tips it would be greatly appreciated!
