Yes (some other way): use Trace Reference with a (fake/temporary) layout containing the placed schedule. You cannot place a viewpoint (or view) such as a schedule physically onto another viewpoint... but Trace Reference gives you a way of seeing both. You will need to click the refresh/update button for the referenced schedule to update its contents as you change items in your plan view that would affect the schedule.
It might be just as fast though just switching back and forth from your plan tab to the schedule tab.
