Why not automatically categorize images?

[Former user]

Hi Magnus Manske, thank you for WikiShootMe, I really appreciate it! Just a suggestion: when I add an image to an item which has already a category, I would like this category to be added to my file directly by WikiShootMe. WikiShootMe is great to upload quickly without using the Commons UploadWizard, but I need every time to return to Wikimedia Commons to categorize my files. It's uncomfortable and chronophage.
