@jeremystretch commented on GitHub (Sep 10, 2018):

Creating an IP address does not necessarily indicate that its parent prefix should also be created in NetBox. Further, providing a hook for this would greatly complicate the view logic currently in place. The development burden would not be worth the minimal gain in convenience.
