If I add another adult to Family Sharing, can I allow them to also authorise child purchases/downloads?

Hi there,

As per the title, can I allow my wife to also authorise child purchases if I add her to Family Sharing?

Currently I'm the organiser and it's becoming a real pain being the only one who can authorise child purchases/downloads. I have two kids so it's doubly annoying!

Surely it's possible to grant my wife the ability to authorise alongside myself?

Cheers
