If you don't know what I mean from the title here are some pictures to clear things up:
On the left you see that by rotating the same right wedge brick by 180 degrees, you can make a smooth diagonal shape.
However, in many cases I found that the space it takes up is to large.
On the right, I stacked the two on top of each other to simulate what it is that I'm looking for.
It would take up only 3 bricks in width instead of 4.

Here is an example of what the individual brick would look like in the case of a left wedge. (The one on the right)

If you think you could do this, please do. It would be of great use to me, and I'm sure many other players.
Also, it would need to be done for both left, and right wedges.
Thanks in advance.
