heliostat geometry

Recently, when I was using SAM software, I found a problem. For the heliostat setting part in CSP of photothermal power station, the geometric shape of the model seems to be only rectangular. Although the size can be modified, there are various shapes of heliostat, such as regular pentagon, sphere, oval, etc., it seems impossible to simulate other situations. But it's also possible that I haven't discovered that 2022.11 has this feature that can change the shape of the collection. If anyone can give me the answer, thank you very much
