I am using ARCXT to program a new BCD996XT for the Minnesota statewide public service system (ARMER). If I select all the system talkgroupIDs I need, they import with group headings from the RR listing (like Statewide Interop, Zone 3 Interop, Minnesota National Guard, etc) and since there are numerous headings only the first 20 "groups" get imported. Is there a trick to get all the TGIDs to import as a single (or a few) groups so they can be organized using the ARCXT memory channel editor? I see that RR will export a csv-file of talkgroups. Can I edit/organize that file and then get ARCXT to import TGIDs from there instead? How do folks handle this task?
