I don't think there is an arg for that. I have written a tangler that
reuses a lot
of the org-babel machinery and has a more flexible mechanism to decide what
to do with the tangled code -- I use it for example to not write a
tangled file if it
hasn't changed, meaning that it will not trigger recompile.
The project is private now but if you're interested I can give you access to it.
What exactly are you trying to do?
