Setting labels when uploading additional Files in the review stage via “Add files”

[janis711]

Is your feature request related to a problem? Please describe.
Currently, when uploading additional files during review rounds in the review stage (not via the document management), there is no option to set labels for these files. By default, a label “Review file” is set. We would like to be able to set labels in order to differentiate between different being reviewed.

Describe the solution you'd like
Option to assign labels when uploading additional files under “Add files”
Perhaps also the option to provide pre-defined labels for users to choose from.
