manually manipulate "date modified" field?

I have a folder, that within that folder, items are listed by date modified. Great, that's exactly what I want. But, I have one folder within that folder that I'd like to always be at the TOP of the view. The folders go back to 2013. Is there a way to manually change that one specific folder's modify date to xx-xx-2012 so it will always remain at the top?

I've already run the reg fix to turn off auto-arrange, so, I can manually drag it to the top of the folder, but, randomly every once in a while, it returns to it's "proper" place by date.

Thanks all!

This certainly looks like it will do the trick, thanks much!
