Can I put the start g-code before heating?

I would like to complete auto-leveling and move the nozzle to a safe position before heating. I have added the g-code as start g-code, but unfortunately, the start g-code is always added after heating, I have to modify the g-code every time after generated. May I know if there has any way to put the start g-code before heating? Or it's it possible to disable the generated code for heating, and let me insert them inside the start g-code with some parameter for temperature?

Cura checks if the start gcode contains commands to heat up the hotend and bed before the print is started. If the start gcode does not have command to do that, CuraEngine adds the three lines (M190, M104, M109) before your start gcode just to make sure that the hotend is not cold before starting the actual print. If you don't want Cura to add these lines, make sure your start gcode contains lines which have {material_print_temperature_layer_0} and {material_bed_temperature_layer_0}
