You can do that in the last version: in selection mode you can press
Ctrl+mouse click to start a selection rectangle, and click again to end
it. Then you can use Shift+mouse click to un-select some entities if you
want to.

The idea behind the way Gmsh handles STL input is that it actually
reconstructs a geometry from it (by detecting sharp edges). So all (or
most) of the surface identification is already taken care of.
