Is there a way to add options only for config files?

[senr80]

Hi,

I'm trying to use CLI11 to set up a config file (many settings for different subsystems) for my process. As there are many settings for different subsystems it makes not much sense to have them on the command line.

In the list of "option options" I found ->configurable(false) which disables the use of an option in a config file. How can I achieve the opposite of it, so an option would only be parsed from a config file?

Thanks in advance!
