Cancel print operation and reset

[digital0785]

would it be possible to when you hit cancel it to auto home all axis or run through the end g code ? every once in a blue moon when i cancel if i go to start the next print it wont home first so it'll raise into the hot end.. It seems to be layer related if i wait a bit it'll operate as I expect and when i start the next print it'll go home then raise up. Also when you're adjusting things from the screen is it possible to add a reset button or like 0 and 100 buttons ? just to make it easy to go back to standard settings. I know it's a silly request but wasn't sure if it was possible

this is my start g code

G90 ; use absolute coordinates
G1 Z130 F600; Move bed down to allow safe movement of nozzles lo left front
M140 S{material_bed_temperature} ; Heat bed up to first layer temperature
M104 S{material_print_temperature, 0} T0
M104 S{material_print_temperature, 1} T1;
M190 S{material_bed_temperature_layer_0} ; wait for bed temperature to reach e.g. 55 °C
M109 S{material_print_temperature_layer_0, 0} T0
M109 S{material_print_temperature_layer_0, 1} T1; wait for hot end temperature to reach e.g. 210 °C
