Choose if YouTube videos are "age restricted"

Currently posting videos to YouTube gives me the option to choose if my videos are “Made for Kids”. This has a different meaning for videos than being “Age-restricted”, and is a different option in a video’s settings entirely.

Buffer’s own marketing library page explains these options incorrectly:

Buffer will show you all the details you typically need to add for YouTube videos – title, age restrictions, category, visibility, and so on.

I would like the option to automatically age-restrict certain videos. Currently I have to re-edit videos through YouTube after they post, to age-restrict the ones that need it.
