Program an IQ omni drive for autonomous

I am trying to figure out how to program for diagonal movement of an omnidirectional drive, This is the “H”-shaped drive with a sideways wheel in the center. Any ideas or examples?

Can you explain what you want, like a custom block, or a series of blocks, or whatever is easiest?

(I have classes so I might take a while to respond, sorry in advance.)

Here is an example if you want a Custom block solution. (and are using 24" wheels)
