Feature request - Preheat to 170c

It would be awesome to have an option to preheat to 170c/60c for PLA since the bed leveling routine runs @170c.

Likewise, apparently something is in the works https://github.com/prusa3d/Prusa-Firmware-Buddy/issues/321

Edit a Gcode file and keep it on your SD card! 
It just needs the beginning  of a normal print... to be cropped off an actual print. and saved as Preheat PLA -170C .gcode

a bit like the attached file,

which when run,

homes the extruder,

moves the extruder up 5mm and towards the middle of the print bed, in order to establish a regular starting point,
to overcome Minda Temperature sensitivity variation. 
the Gcode then sets the extruder to heat to 170C  and 
Sets the heatbed temperature to 60C and waits for those temperatures to be achieved. 
when the temperatures are correct, the printer should 'BEEP' 4 times, to alert the user that it is ready
and then start a 2 minute timer. at the end of this timer, 
The Printer Beeps twice, and begins cooling down for safety reasons

I hope this helps.
I have tested it on My Mk3, bu I don't have a Prusa Mini to try it on. 

I put the file in a sub directory labelled 'Test" on my SD card, so it's easy to find... 
I keep my first layer configuration files in this location too...
