There's no way of creating some kind of restrictive or exclusive burrow?
An anti-burrow? ("All those so assigned, do
not take any job[1] within this area!") No. You can only make 'inclusive' burrows, and (alerts aside, I must admit I've never used them) the sum total areas of all burrows a dwarf is assigned to is their stomping ground when it comes to finding things to take things from/take things to/do things with in. Unless they aren't assigned to
any burrows, in which case it's the entire accessible map.
(I'd rather like a "If other burrows are assigned, add this one, but don't bother otherwise" method, actually. Easier than either adding in the relative sleeping/sustenance areas to each and every work-related burrow or setting up sleeping/sustenance burrows but also remembering to activate them/de-activate for dwarfs as I start adding them to other burrows/remove the, from their final work-burrow. I could see it being a tag in the relevant assignment screen (usual enter to toggle, but another key used to qualify for such a "but only if..."). Either that or tag the whole burrow as such for everyone, but my original suggestion gives one a way to exert fine control (e.g. keeping some workers
only in their workshop areas, dissuading them from seeking sustenance while an emergency job needs doing), and there's plenty of unused space/key-bindings in the burrow-assignment screen. It would also allow such anti-burrow assignments as I think are being asked about.)
