Reversing thread display order for selected forums

[CMilne]

I am trying to reverse the thread display order for a few of my forums.

Via templates I have made a few of my forums appear as episode guides and it looks completely different. However, I add the episodes in ascending order ( e.g. 1, 2, 3, 4 ) and they display descending ( as per usual ). I need to change this so I can post in ascending order, and it displays in ascending order but for the selected few forums only, so it cant be a global setting, and I also need it so users preferences cant override the display order.

Any and all help much appreciated.
