If instead it is desired to build a Phase-2 program from scratch, there should usually be a really, really, really good reason for doing so. And even then you probably shouldn't do it. Even if generation from a Science Goal does not exactly produce the desired SB, it should usually be the case that an approximate version thereof can be produced and then edited. If this is for some reason not deemed possible, then a Phase-2 program should be created, either via the toolbar or the File menu and the various elements (described in the next section) added by hand.
