V5 VEXCode Configuring drivetrain with more than 4 motors

Wondering how to set up a holonomic drivetrain that would contain more than 4 motors. In the past (using robotC) I would generate variables for different channels (1,2,4…) then set each motor to the different (+/-) variables in order to have motors spin in appropriate directions when the channel on the controller was pressed. I can’t seem to figure out how to do that with this new coding software. ny help would be greatly appreciated. Thanks
