How to program three motors onto one button on the controller and how to make them spin at the same time using Vex V5 Blocks?

Hi my team is using a 3 motor flywheel this year and wanted to know how to program it onto one button and make them spin at the same time using vex v5 blocks.

you can have a function that activates on the button click, and have it spin all three motors at once. I can give you some more detail if you snip the code and paste it here.
