New Folder Function for Attach File in SaveIt

Currently, Concourse task only has pre-created folders for file upload to SaveIt function. Concourse could add a function within file attach function giving option for user to browse existing folders/create new sub-folders within those pre-created SaveIt folder to upload file. Currently, every time there is a new additional file added to SaveIt via Concourse task, every files marked for add to SaveIt previously are also uploaded if they are organized in the sub-folder instead of in the pre-created folder. This created duplicate files in the SaveIt repository.
