Use a custom file other than `bower.json` to install dependencies

Question

How can I tell bower to install my dependencies from a custom file (say my-custom-deps.json)?

dir/
  --bower.json
  --my-custom-deps.json
  //other files and folders

There is no command like bower install --use-file my-custom-deps.json right?

Why?

I want to build the app with:

1. An older version of a dependency
2. Latest version of that dependency

in my gulp task.
