Honored ContributorGlobal signals that automagically drill through the hierarchy is not only a poor practice assuming your tools would allow for it (never seen it myself for good reason) but it would open you up for all kinds of nasty bugs where things would get wired up that you were not expecting. If you find you have signals running all over the place in your schematics at various levels perhaps the granularity of your design is causing this.
I would also take a look at conduits, you might find them handy when interconnecting various block diagrams in a design.
