Chromecast Group command line

VLC version 3.0.2 allows for Chromecast streaming of a single IP. No command line option for a Chromecast group or multiple IPs. There is no means of storing the Chromecast group selection as default on VLC startup. My workaround has been a VB script that starts VLC and passes keystrokes for "Playback" (alt-l), Render (r), and then I pass multiple [ARROWDOWN] to hopefully select the desired group. This isn't dependable because the Chromecast scan list is in no particular order other than by discovery. Any of these would be a great enhancement: 1)Command line for groups or multiple IPs. 2)Allow Chromecast device/group to be set as default at startup. 3)Alphabetize discovered device list to allow consistent ordering.
