The short answer afaik is that you cannot pass arbitrary options to a
new screen session while starting it; you have to create a screen and
then use -X to send commands to it.

If this is a common problem, it might be worth looking at adding
something like ssh's "-o key=value" syntax. The only problem I can
forsee is that command lines could get ridiculously long…
