Hi Keith,
In the short term use the method Greg has described above. As Greg mentioned I am working on some additional tools that will allow you to start with a tall Standard Base cabinet with no drawers or doors. The, with a few new tools such as Insert Drawer and Insert Door you can place doors, drawers, dividers, shelves, rails and stiles anywhere you wish. The full suite of tools will take a while, but the doors and drawers will be available in the next release, about two weeks away.
Joe….
