For the File application, is there any mechanism to limit upload capability to only those that belongs to certain groups/projects? The idea is that we don't want to allow for everyone to be able to upload huge amount of files, we only want a few limit people in our release team to upload sw packages that then everyone can download. I know you can fine grain restrict to who can see the uploaded files but I couldn't find an option to restrict the upload operation, but maybe i wasn't look hard enough.
