'New Child Post' button from parent post without using Attribute drop-down

Hi,
I have a custom post type “my_custom_post_type” which contains posts using a grandparent > parent > child hierarchy. I am currently using the ‘Attribute’ drop down to assign a new post to a parent post but due to the amount of posts I have this is getting very confusing.

I was wondering if it was possible to add a button to a parent post which says ‘create new child’ from the current parent post.

Example Post Hierarchy
– Grandparent Country
– Parent City
– Child Suburb

When on the Country post page I would like a button that says create new city. When on the City post page I would like a button that says create new suburb.

Thank you for your help 🙂
