If you really want to get fancy, you can simulate funny surfaces piecewise using extra vstab objects. But in practice, that's very unlikely to be useful. YASim isn't a fluid dynamics simulator, which is basically required for turning details like wing planform or airfoil shapes into actual performance data. And in practice that kind of shape data needs to be far (!) more accurate than a typical 3D model polygon mesh. If you have the software and the micro-detailed mesh, then that's clearly the way to go. But for interactive flight simulation, it's just a non-starter. In principle (modulo bugs and configuration glitches, obviously) a well-configured YASim model generates aerodynamic results that are about as good as you can get without access to the original design plans or test data.
