How do I use telegram-send to send to different chat_ids without an actual file?

[sundarkast]

I want to send to multiple users but don't want to put bot token in each file for security reasons. Is there a way to specify a single global config file with the bot token (/etc/telegram-send.conf), but specify the chat_id separately on command line?

Following doesn't work either:
telegram-send --config test.conf -g "test"
Missing options in config: chat_id

Thanks!
