Welcome to the forum.
No, this will never happen. The main reason is time: It took me 15 years to get to the point the SP-Studio is now. So if I'd decide to draw everything again for side- and backview, this would mean several years of no other updates until I'm done. My visitors would not like this and it would be a very boring job for me.
So I think it's better to focus on adding new items instead of drawing the old items for different views.
This would be different if I was working with 3D models, because you can just rotate them. But my drawings are just regular 2D drawings, so every view means extra work.
