Bump,
I have looked at the Gcode. Although you can change these settings under Extruder, Coast at end and retraction/restart distance it does not change where the M101 and M103 are placed.
This causes major issues for me also as I am operating a valve which controls the flow of plastic.
I am sure this would be a major issue for the guys running laser cutters also.
Someone posted this link elsewhere which may be of help.

It is pretty painful that a paid program does not support this when others do.
