Problem

When using "Create knowledge base article", it's possible to add a title and select a template, but it's not possible to select the parent page. 

The new article is automatically created on the space linked to the Service Management project, then after saving the article, it's necessary to move it under the desired parent.

Suggestion

Besides adding more templates (as already suggested here), add the ability to select the parent page from the "Create knowledge base article" pop-up window.
