Link or Append Hierarchy

Hi all,
How do you link or append a hierarchy…
Say you have a multi-part model thats in a hierarchy in a.blend and you want to get it into another blend where you have a rig, how do you bring it in without distroying the hierarchy…
I seem to only be able to import single objects, hence I have to reparent them in the new blend files.

on a side note , is it possible to select an entire hierarchy in the outliner by selecting the parent?
Thanks

When you want to bring in a multi-object structure including it’s control armature, use the RMB in the Append/Link window to select ALL of the objects in question at once. Then hit the button to grab them en masse.

Thanks Harkyman,
Thats what I did, but they come in as separate objects, not in the hierarchy .
