Feature request: access to pre-init gcode

I'd like to have access to pre-init gcode.

Current simplify3d inserts something like this before the user init gcode:

G90
M82
M106 S0
M140 S60
M190 S60
M104 S240 T0
M109 S240 T0
M221 T0 S100

In order to prevent massive oozing during initial extruder heating, i'd like to be able to do something like

G28
G1 X0 Y10 Z0 F2000

immediately after the M82

This puts the extruder nozzle touching directly on the build plate, blocking the nozzle off during heating.

It saves a huge mess, and would be nice to have supported in simplify3d.

You can already do this. Just use the [extruder#_temperature] or [bed#_temperature] variables as explained at the link below.
viewtopic.php?f=8&t=1959

Then you can control exactly where those M140/M190/M104/M109 commands are placed.
