skip subfolders

I tried searching for this in the forum but couldn't find it....I have a subfolder in my Applications folder that I want launchbar to not index (skip). I can't seem to locate this feature/option in the index options for the Applications folder. Is it there or is it even on the roadmap?

To clarify, I can skip subfolders for a new folder I create but I need to skip a subfolder in the Applications folder, which the option is not there for.
