upload a file to a specific bucket in storage

Hi Ben.

First, thanks for this amazing product that is really easy to use and helpful.

I was thinking of adding a feature to upload a file to an specific bucket in storage. Maybe in options there might be a field called "customBucket" or something, and if that's true, the default docPath will be replaced with that bucket and will be upload there.

What do you think?
