Feature request: enable fan during nozzle change

Details: Under Print Settings> Multiple Extruders>Ooze Prevention add a check box for enable fan during cooldown

Reasoning: Although ideally the cooling fan should not cool the nozzles, in practice it pretty much always does. This feature would take advantage of that cooling to help accelerate cooldown during a nozzle swap, thereby further helping to reduce ooze

Current workaround: Under Printer Settings>Custom G-Code>Tool change gcode you can add a fan command ie m106 s255, however this occurs just before the temperature change initiated by the ooze prevention system and there is no way to turn it back off once the temperature change has occured. You could manually code the temperature changes into this section, however if you are switching filaments with different temperatures you would need to code for each configuration of filaments.

In a well built printer, the cooling fan does not cool the nozzle. Trust me, such printers do exist
