Cómo controlar la Bibliografía numerada y el año del autor en un solo comando

Question

Estoy usando el paquete natbib. Me gustaría controlar el estilo del babero con un solo comando \numberedref.

Mi requisito es que si el \numberedrefcomando está disponible en el archivo tex, el resultado se muestra enlista de referencias numeradasTodos los enlaces de citas deben aparecer numerados. Si el comando no está disponible de forma predeterminada, se debe mostrar la referencia del año del autor. Esto es lo que va a ocurrirsin cambiar los elementos de la lista de referencia como\bibitem[Sabatinis et al., 1999]{Sabatini:1999}

Pero no sé la idea cómo controlar el comando único definido por el usuario\numberedref

Mi archivo tex a continuación menciona:

\documentclass[twocolumn]{article}
\usepackage{endnotes}
\usepackage[noblocks]{authblk}
\usepackage[switch]{lineno}
\usepackage{mdframed}

Patterning in Arabidopsis root development is coordinated via a localized auxin concentration maximum in the root tip (\citealp{Sabatini:1999}), requiring the regulated expression of speciÞc genes. This auxin gradient has been hypothesized to be sink-driven (\citealp{Friml:2002}) and com- putational modeling suggests that auxin efßux carrier activity may be sufÞcient to generate the gradient in the absence of auxin biosynthesis in the root.
