XF 1.4 Show all threads by last activity after clicking on tab

[zeropaid]

I have several main nodes that have 3-5 sub nodes. When a user clicks on a tab it takes them to sub nodes list but I would like to display all the threads from it's children with the sub nodes listed above.

Is this possible?
