Add the possibility to label in data browser

Is your feature request related to a problem? Please describe.
When testing around/Scrolling through the data browser being able to add a label right then and there would help with the workflow. Jumping into the session and back without saving the filter as a slice is pretty much impossible. Even with a saved slice, the current position needs to be “found”/scrolled down to again.

Describe the solution you’d like
Being able to assign a label in the data-browser (possibly for a subset e.g. Only Full Record - Classification tasks)

Describe alternatives you’ve considered
The current workflow
