Can entries of type structure have multiple parents?
https://docs.craftcms.com/v3/sections-and-entries.html#sections says that they can be hierarchical, but the UX doesn't seem to let me have more than one parent for any given child structure.
Not sure if that is a hard limit or just something misconfigured on my end.
I searched around a bit and saw this answer: Structure entry connected to multiple parent entries which implies that the way to do this is to use relations, not structures, but wanted to confirm.
