Thanks, Maxim! This was helpful.

However, I'd like to discuss the concept a bit further. We're talking
about changing only one property for a single location while keeping the
rest of the configuration constant -- a pretty common task I guess --
shouldn't there be a more elegant solution?

Cheers,
