Since post processing of parts has individual effort, it would be nice to give each print file a seperate labor time and then add this to the general time from the printer that is needed for each print, like changing/cleaning print beds and so on.
Also it would then nice, to add the individual times for starting a print and changing filament seperately to the global statistic and only when filament actualy needed to be changed and not apply a single amount of work time per print.
