It's difficult to create many deployments of similar but not identical collections of zarf files

I'd like to be able to do something like:
root
small.zarf.yaml - import x,y
big.zarf.yaml -import x,y,z,a,b,c,...
x
x-deploy.yaml
...
...
and use the command
zarf package create small.zarf.yaml to create the small package.
and
zarf package create big.zarf.yaml to create the big package.

Describe the behavior you'd like

• Given a file path exists with a zarf file that can be built.
• When zarf package create ${the file}.yaml
• Then a zarf package is created using that file. No change for the default behavior of package create.

Describe alternatives you've considered

I'm fine with any number of possible solutions, including
zarf package create --file theFile.yaml
or
zarf package create /the/path/to/the/folder/with/the/file/
as long as I can point multiple files to the same root setup.
I prefer the complete path to a file option over a directory, but supporting both would be nice (though the directory option is not one that I'm super excited about, if it were dropped I wouldn't care).
