I have a question if anyone knows how to make the default slot have a beginning, middle and end as a different element. I have tried everything, I managed to do it by connecting the beginning and end to the corners, but I need another solution, because I want when modifying the spline I would like the beginning and end to be always in the same place and only the middle should expand. The spline is closed so I can't use separate start and end slots. I have shown in the images below what I mean.
