TOC Page Numbering in Appendices

I have to number an appendix A-1, A-2, etc. I have a separate table of contents set up for the appendix. I cannot get the TOC to acknowledge the “A-” part of the page numbering & have to manually paste this into every TOC entry (which is excrutiating on long TOCs). I have tried every field trick I can think of. Does anyone know how to get the TOC to display the “A-“? My current setup for the “A-” is like this: { QUOTE “A-” { PAGE } }, but it won’t show the quoted item in the TOC. Thank you!
