Child items can't be deleted by editing parent record


I already raised this question last year.

Given a parent record and some child items the child items can’t be deleted when EDITING the parent record. Why upper case editing? Because when you first add the record and the child items, the child items have the option to delete them. After you save the parent record and it’s child items and then edit the parent record, the option to delete the child items is missing.

Why is this behavior set like this? Is there a chance to fix this in the near future or there’s nothing that can be done? It’s a useful feature for me.

Thank you!
