[feature] Add way to modify sample id preview

[davebulaval]

Add a way to change the sample id output in the annotation process to a specific number (see picture).

Reason: I want to annotate large text and the app don't like it when the documents to annotate are too large, so I spitted in a sentence the document but I would like to be able to offer to my annotator the context (i.e. a document id that they can use to retrieve the complete text).
