Thanks for the feedback Brad, but I found a better solution where I was able to use my customized locator style from v9.3.1 in v10.0.
I made the mistake of copying the .loc, .loc.xml, and .lox files from a v9.3.1 box thinking that I would recreate the address locator in v10.0 from these files. I thought I would see the style I was looking for in the Address Locator Style dropdown box, but it was never available. I then copied the .lot style file from v9.3.1 and I was then able to get an address locator where it asked the user for an address in 1 input box and a zone in a second input box.
