Describe the feature

This is probably a fairly niche idea, but I am working on a roof that uses two different angled slopes (part is using the panel slopes, the other part is using the standard slopes), but where they intersect and form a corner, there is no clean way to transition between them. I thought that the collapsible block might be able to handle it, but the shape is too complex to achieve there.

Here is an example of what I am referring to. The right side are slopes, the left side are panel slopes. This is likely overly complicated because of the two block nature of the slab and panel slopes, but this is what I get for making strangely shaped buildings, lol.

This is unfortunately not viable. The amount of variations needed to cover all possible combinations of slopes, slope slabs and slope panels would either lead to a very large amount of additional blocks or a few blocks with overly complicated and annoying placement behaviours or, in the worst case, both.
