Feature request: Add points location in canvas_result.json_data for freedraw drawing mode

[gn-hiro-v]

Hi there,

Thank you for a very great tool! I really enjoy it.
However currently I'm trying to create a model that needs point coordinators with freedraw mode in order to put in the form of List[List[List[float]]] for the representation of a sentence.

Is there a way to do so?
Thank you
