Yes, that is the correct place I was referring to.

Finally, the PrtScn(s) of my original submission attempt that failed- notice how there's no way to recover any of the files. Once you click "Submit," if any process fails, there's no retrieving any of the data/descriptions you submitted, it's just lost.
This is why I'm proposing that the setup be modified to fully upload the images to WikimediaCommons (to completion, so they're part of the database), and then let the "Describe" step of the upload process simply attach supplemental information/metadata to the file. This way there's no loss of upload when errors occur and the submission process fails.

Here is a PrintScreen from the multiple-image upload I attempted to do, but that failed and wouldn't allow me to correct the problem and resubmit. Notice the lack of buttons in the bottom right corner, or clickable links to fix the problem and resubmit; only starting over from the very beginning.
The red "!" (in place of the green checkmarks of the other successful files) should be clickable to fix the problem.

Note also how along the top bar of the submission process the steps are 1. Learn, 2. Upload, 3. Release rights, 4. Describe, 5. Use.
Currently it isn't possible to click a previous step or "back" button to revert to an earlier page. This makes it such that if a mistake occurs, it's just game over, start from the beginning.

See the bottom right of the PrintScreen - it should have buttons (options) in place of where it currently only has text describing the failed process (a "dead-end" so to speak).
