I'll create an importable XML for you but....
You really need to plan this out correctly! System Planner? You can't just pick values off the top of your head and throw them into the radios.
I have an Excel template. There are columns for the Alias, MDC ID, Astro25 conventional ID and Astro25 trunked ID. I've made it so if you enter a value exceeding a limit, it will tell you in red. It will also highlight, in red, any duplicate values. When you're done filling it out, nothing should be red.
Message me your e-mail and I'll send you the Excel template. When you're done filling it out, send it back and I'll run a script on it that will automatically create an XML you can import. It will assume your Astro conventional system is the default (Cnv Sys 1), your analog is "Cnv Sys 2" and, if applicable, the trunked system is "Trk Sys 1". You can edit the XML in a text editor using CTRL-H (usually) to find and replace those values if you have named them something else already.
