Better Separate Mesh Vertex Assignment

I have had to do some simple rigging lately. I have noticed Blender does not seem to take kindly to separate meshes. Particularly when you going through the vertex list and hitting assign or remove. Say I have a bone affecting multiple mesh objects. I should be able to select all go into edit and then unassign the vertex group to whatever is selected instead it is ignored on everything except the last thing I selected to enter edit mode for vertex reassignment surgery. I kinda wish to suggest this to be bloody fixed.
