When suspending a print with gCode "M600" or "suspend" command for filament change,

When suspending a print with gCode “M600” or “suspend” command for filament change, the standard-setting turns off the heaters.
Documentation for suspend-command says “Heaters: Turned off if option enabled (default)”
But I didn’t find any information about keeping the heaters on. What do I have to do to let the heaters continue to heat during this pause-modus?

There’s an option for heaters on during disable.

Yeah, that is what I already wrote…

leave_heaters_on_suspend is a config option

Thx for the info
