When dragging and dropping an assembly into an assembly, thus creating a sub-assembly, envelopes in the sub-assembly are hidden even if they are shown in the original assembly.  Is there a way to change this default behavior?  Also, if I drag and drop a bunch of assemblies into an assembly, I cannot select all of them and then show the envelopes.  I have to do one at a time.  Anyone know of a workaround for this?
