I'll be honest, I never paid attention to that on my previous devices as I don't use that feature. Samsung provides it's own contacts app though and I don't see NEARLY the amount of complaints (if any) about this missing feature on other device forums (well, Pixel and nexus as that's where I usually visit).
I suppose I could try flashing my Nexus 6p back to Nougat to see if that field is there...
