Spans question in Feedback datasets

[davidsbatista]

I need to annotate data where for each document I need to annotate named-entities (i.e., token level classification) and also a set of labels (doc-level classification)

How can one achieve this with rubrix, as far as I understood you need to have two different collections, for the two different tasks, and then, after annotating and exporting them, you need to merge the annotations.

Is there any way to have this done inside rubrix - also on the interface?
