Problem

Currently, there is no way to achieve the below page hierarchy using the automation rules.
1. Business Case
2. Design
> 2.1 UX Design
> 2.2 Architecture
4. QA

Using the "Publish New page" action and selecting the Space as "Page from this rule's space" I can only select "Current Page in rule" which will consider the page in the previous page as the parent page.

With the above setup, I am able to create "UX Design" under the "Design" page. However, I am not able to create the "Architecture" page as the child of the "Design" page. Hence, ending up with the below hierarchy instead.
1. Business Case
2. Design
> 2.1 UX Design
> > 2.1.1 Architecture
4. QA

Suggestion :

Request to add a field in the "Publish New Page" action to select the Parent page instead of the current default "Current Page in rule" option.
