CLI option to load stories from specified directories

[ZorGleH]

Is your feature request related to a problem? Please describe.
I use Storybook in a large multi-project/libraries codebase. Sometimes I'd like to run only stories from specified directories, because my computer takes several minutes to load all the stories. Of course I could do that from the config file, but it would be much more simple to have a CLI option for it.

Describe the solution you'd like
I'd like an option to run stories from a given directory. e.g. start-storybook -d ./path/to/stories/**/*.stories.tsx,./another/path/to/stories/**/*.stories.tsx

Describe alternatives you've considered
Passing different config files with -c option, but it is not flexible enough because you have to edit or add a new config for each case.

Are you able to assist bring the feature to reality?
Why not! It would be great if you could tell me the best way to do this.
