XF 2.1 Display Threads beneath Nodes when clicking on Category

[xkcd4any]

Hi there!
I was wondering if it is possible, that when clicking on a Category Title, instead of just showing the Nodes (Forums) within that category, to show both Nodes (Forums) and all Threads of those nodes (Forums) beneath the nodes.

Kind of like what I think is possible with Forums and Subforums, but with Categories.

Thanks!

That would require custom development.
