Enable Host Action Commands

I was wondering if there is any way to enable host action commands when using the custom firmware builder, or if, by any chance, it is already enabled in any of the pre-provided firmware? Sorry if I missed something somewhere, but I could not find any information on this!

Thanks in advance for any help anyone can provide!

Host actions should be enabled by default on both the daily builds and the custom builder.

If not, its a bug - so please report it.
