How to pass --set-file using helmfile

Hi Team,

We use --set-file flag with helm but the same is not supported in case of helmfile. I have tried all the ways by using set --state-values-file, --state-values-set, --state-values-set-string but none of them worked as same as --set-file flag.

We would like to pass an argument like --set-file foo.bar=/path/to/file. Please suggest.
