Display value of POC in Volume Profile Drawing Tool

Currently Point of Control POC in Volume Profile drawing Tool is shown as yellow line.without showing the value in number. in order to see the value in number, user has to zoom in the price axis until the tick (which is very time consuming). would request to show the POC value in number along with the yellow line (might as well show the number of Value area high and value area low).
this is specifically for drawing tool - volume profile, not indicator
thanks for considering
