Please add functionality to set extruder fan speed and print speed for each extruder/tool rather than universally.

This would make it far easier to configure dissolvable support material. Sometimes PVA needs to be printed at a slower rate with far less cooling to the primary extruder to get it to adhere. Currently this needs to be changed manually on the printer once the print starts. It would be good to set these as part of the config.

You can change the fan speed based on which extruder is active by utilizing either a toolchange script containing IF statements or a post processing script that does a TOOLREPLACE.

Thanks @S3d-Jake, that solves the fan issue.

Is it possible to stack IF conditions like this:
{IF NEWTOOL=1}{if [layer_num]>1}M106 S77 T1; Set T1 fan to approx 30 percent

Can you please confirm if this TOOL#REPLACE line is correct:
{TOOL1REPLACE "; fan speed" "; fan speed \nM106 S77" } - assuming fan speed is the value here?

Is there a similar way I can apply a 50% under-speed to tool 1? I couldn't see anything obvious on that linked thread or anything relating to an ID for "print speed" on the Marlin site.
