How to have affiliation without numbering in revtex?

Question

How do I make affiliation without it being numbered on the last author being numbered too? I want Author 2 to only have the affiliation of Affiliation 2 and the last affiliation to just be a general affiliation without numbering

\documentclass[aps,prb,twocolumn,superscriptaddress,nofootinbib,floatfix]{revtex4-1}

\begin{document}
\title{Title}

\author{Author 1}
\affiliation{Affiliation 1}
\author{Author 2}
\affiliation{Affiliation 2}
\affiliation{Affiliation without numbering}

\maketitle
\end{document}

Answer 1

I don't think that there's a provision for this, but you can hack it:

\documentclass[aps,prb,twocolumn,superscriptaddress,nofootinbib,floatfix]{revtex4-2}

\begin{document}
\title{Title}

\author{Author 1}
\affiliation{Affiliation 1}
\author{Author 2}
\affiliation{Affiliation 2\\Affiliation without numbering}

\maketitle
\end{document}

It works the same with revtex4-1, but I believe you should use revtex4-2.
