Editing of e-mail categories via phone app

On the web page and in the app on my tablet, I can edit the category (purchases, newslettes etc.) of individual e-mails either by dragging the e-mail to a specific category, or by marking it and using the "move" button.

However, on my mobile phone the option to move an e-mail to a category is not available. I can select one or multiple mails, but the move option only allows me to move to other folders, not to other categories. Also the drag-drop is not available.

It would be nice, to be able to re-categorize e-mails on my mobile via the mobile app.
