The official SDL docs and the CME state/show that a keyword can have "parent keywords" (multiple), also, I've read about that from various sources, and it's even explicitly mentioned in a comment herehere. Despite all that, I am unable to add multiple parents to a keyword from the CME, so I'm wondering if it's possible at all? I can imagine doing it via code.
I have no practical reason why I would want this, I'm just being curious.
Thanks.
