Appendix-only table of contents in Revtex

I am working with the Revtex document style, and would like to add a table of contents to the beginning of my appendix which excludes reference to the main text sections. How can I go about doing this? Some solutions I've seen use the scrartcl document class and do not work in my case; I am using \documentclass[aps,prx,reprint,showpacs,floatfix,superscriptaddress]{revtex4-1}.

Note that I do not want to include a table of contents at the beginning of the main text, I only want a table of contents at the start of the appendix, showing only the sections/subsections contained in the appendices.
