Disk and name destination

[nam-co]

Hi, thanks for the package, is been great using it, I was wondering if its possible to:

1. Specify the destination of the (css,js) file to example a S3 bucket? this would be great and save a lot of time

2. Config that the name is always the same, so every time we change or add a css file it doesn't output a new css file, instead it replaces the same and maintains only one

Hope you consider this, I prefer to use this instead of Elixir

maybe something like:
->withFullUrl()->withDisk('s3')->withFileName('great.css')
