How do I apply a callout for a threaded fastener, in a drawing

(In a drawing, in Onshape) 
I need to specify the thread of a fastener (screw, bolt, threaded rod, stud, hanger bolt...)
I am not interested in drawing a helix or something else, nor do I want to have a realistic look-a-like thread.
What I need, is a standardized simplified representation of the thread, i.e.: that the fastener's drawing has a thin line to represent the root of its thread, and a callout next to it, with the specifications of that thread.
(see also the image below)
I know how to do it for a hole (there is a specific icon/command in Onshape, "Hole callout"), but I couldn't find anything similar for fasteners.

Thank you 
Dan


What I need, is something like this...

    There is not parametric way to do this for external threads. You will need to note it with leaders manually, and draw your cosmetic threads on a sketch in the partstudio and show it it the drawing

    I have voted for the Improvement Request "External Cosmetic Threads", which describes an issue similar to the one I have.

    If you have a similar problem, please vote as well. It is sitting there since 2017 and (as of today) it is in the top 5 of the open requests...

    This is a much more important feature then visual external threads, as this would make a drawing look right. Today I am not able to draw threads for machining purpose like you show in your picture with M24 and M14.  Where can I Vote for such a improvement.
    There should be a Hole feature with threads, but for shaft.
