Precision_threshold in Timelion visualization

Is it possible to add a precision_threshold to a Timelion visualization? I don't see an option to add JSON input to this type of visualization.

Hello.
My previous answer on that was wrong. You can only add extra params to the Query object of the request, but not to the Agg object (where the precision_threshold is supposed to go in). Currently there isn't any way of adding it without touching the code for Timelion.
