I am using FileIFrameField and ImageField in various classes of my site. It seems to be a known issue that you can't select a different directory other than "Uploads" to upload your assets to. I noticed that you can create a new folder in the "Files and Images" part of the CMS. From there you can upload assets to wherever is needed and select the asset at the page level. My questions is: can you disable the radio button on these field types labelled, "With one from your computer"? My thinking is that this will force the editors to use the form on the "Files and Image" part of the CMS to upload new assets. They will still be able to use the "With one from the file store" option for selecting existing assets.
Or, has the issue of selecting a different directory to upload assets to been fixed?
