PWNCNC/MODBUS Start/Tool Change G Code settings

So I switched from a Makita Router to the PWN CNC 2.2KW Water Cooled 220V Spindle. What I’m trying to accomplish is that the spindle does not automatically start until I acknowledge the tool/message. I know Vectric/Postprocessor embeds a T0 message. This also sets the speed and issues the M3 start command and opens the window on the display screen. So is it possible to make this not start the spindle until I acknowledge the initial start/cut message, and again after tool change? And if so can someone give me a gcode example of how to do this?
