[galaxy-dev] is it possible to upload files to different local directories based on the galaxy upload.py script?

Hi; Is it poosible to upload files to the different local directories by Galaxy upload.py script? It seems to upload all files to the same directory based on the file path in universe_wsgi.ini file. if yes, what part of upload.py needs to be edited? also is it possible to keep name of uploaded file unchanged? Thanks in advance. Amenda Lee
