Is there a way to open RAD only if it's not already open (for IPC commands)?

I'm trying to launch and debug my program with RAD via my editor, but I have to manually open the RAD debugger because if I try to open it via raddbg it will just keep opening new instances every time I press F5 in my editor, for instance.

It would be nice if there was some "ensure_rad_open" IPC command that will launch RAD if it's not already open, otherwise do nothing. Honestly, maybe this should be the default behavior of --ipc without even needing an extra command? What's the use-case for trying to IPC to RAD and having it be completely ignored because another, graphical, instance of RAD wasn't already running?
