Restricting Uploaded MimeType within the File Manager

Permalink
I have a client who would like to be able to restrict the files being uploaded to only Jpeg/Jpg,

Whilst I can restrict this from within the file manager "access" clicking upload still only shows "All Files", I would like to be able torestrict the MimeType of the Upload to only allow Jpegs/Jpgs so that the user is unable to select/upload that PSD or gif in the first place.

Is this possible within the core or do I have to do some editing?

I am not to sure if this is a bug,

I can change the "Permissions" to allow users to "Add Files" this I make Custom, then When as that user I visit the file manager I am still shown all files available.

I have to remove the global file types to be Jpeg in order for the File manager to filter these results to only the jpeg, but as the Super Admin I would still like to be able to add other files.
