Drop Down for multiple Users

Hello,

We offer courses on a family level via woo subscription. With this plugin currently we have parents sign up their child separately under “additional fields” individually. We are looking to add a feature where parents can see a drop down of their multiple children’s and sign up together.

Also how can we set “additional fields” as pre filled when clients login to purchase like how billing is auto filled when logged in.

If these features are part of the pro, kindly let me know!

Thanks
