SFTP entire contents of a directory

It would be great if it would be possible to SFTP download the entire contents of a directory and all subdirectories.

Usecase:
- I deploy a jenkins specifically for non IT business end user's to manage automated jobs, downloads, datafeeds etc. Overall this works pretty well and my user's know how to re-run jobs that fail, change the cron scheduling time etc.
- I'd like to use ssh2easy-plugin to SFTP the entire contents of an SFTP server which contains 3rd party data to which my company subscribes. I tried various wildcard patterns and couldn't get it to work, hence this email
- Single file works fine; but if an SFTP server has 10 or 20 files I'm interested in, I have to manually + explicitly a a build step for each one

Thanks!

Start by locating the existing single-file SFTP download build step in the ssh2easy-plugin code and tracing how its source path is handled. Define completion as downloading all files in the selected directory, including nested subdirectories, without requiring one build step per file; verify behavior against the existing single-file case.
