Among the many things you CAN'T do with a package is link it to a diagram in the same way as any other element... That is, via the ill-named Composite Element menu option.
This means that the ONLY diagram you can link a package to is the one immediately under the package AT THE TIME!
This is not good. It would be far more consistent to allow the package to link in the same way as everything else. That way, the modeller can choose which package to link to on double-click. And the link would be retained regardless of diagram order (just like all the other elements)
