Switching to folder format if a certain folder is present?

I generally use Power Mode with no icons.

When dealing with directories containing Subversion files, I want to use Power Mode with icons, so I can see the overlays.

I've set up a folder format for a specific folder, but ideally I'd like to tell DOpus to switch to Power Mode with icons if it detects a .svn folder inside the one I'm looking at.

Is this possible?

Not possible, sorry.

Something that can be added to future versions, perhaps?
