Reset to "factory" defaults?

A long time ago I modified my Apache Diretives in the templates to support FCGI. Now that the free Virtualmin has that “baked in” I wanted to remove it, but more so, I want to reset my Default Apache config back to the original Virtualmin defaults.

Is there any way to do this easily?

If not, does anyone know where I can always lookup the suggest default values for a Virtualmin template?
