temp calibration for dual head printers

Hi

I have a dual head Snapmaker A350. I have been using the calibration from this page, but the gcode generator cannot deal with the dual head. Right now the simple solution is to download the gcode, open it, and search for commands with T0 and replace it with T1. But if you could include it in the generator as an option it would make my life easier :)

Thanks
