import a saved sketch into the sketcher

Is there a way to save a profile sketch, and then import it into other files to be used to create that part.  Also is there a way to make this sketch or profile dependant on the original sketch or profile?

Here is what I am trying to do.  I have an extrusion that obviously has a fixed profile.  I would like to creat a part by importing that profile instead of having to redraw it every time.

thanks
