You can turn on "ID Search" in Sentinel. If you are looking for I-Calls, there is a thread that explains how to do that in Sentinel as well. Basically, add an "i0" channel to the favorite list you want to hear them on.
bee,
See this thread.
You can turn ID Search on or off, edit system frequencies, edit the band plan (if needed for rebanding, between the weekly database updates), all in Sentinel, then load the updated Favorites list back to the scanner.
