gcode to warm up enclose before printing

On my voron (klipper) i have code which heats up the chamber until a certain temp, and I wanted to know if its possible on my mk3s (marlin) too. 

Basically in the winter/spring it gets too cold and it gets the mintemp error a lot. I wanted to see if i can lower the mintemp (to get rid of that error) and also just use the heat from the bed to at least get the temp up a little before i start printing for the day.

Its a pain having to hold a hairdryer in the enclose until it reaches a certain temp! any thoughts?

RE:

The easiest way is to include a simple dwell time code in the gcode startsequence (set G4 after M190):

 

M190 R[first_layer_bed_temperature] ; wait for bed temp

G4 S1200 ; wait and heat bed for 20 minutes

continue rest of code...

...

thanks dude, most appreciated! just wish the prusa discord was more popular and had the same community as the forum.
