Form Wizard styling

How can I best approach making this with Filament? (see attached image) It's similar to Form Wizard. Main difference is layout and styling; steps are on the left, vertically, and there are icons and subtitles. Can this be achieved with the standard Form Wizard? With custom css on top? If not, is it easy to fetch all Wizard code out of the package and tweak it to my specs? I'm thinking, maybe make the left steps a custom component, and triggering regular Form Wizard step forms? Hiding the default step navigation? An additional requirement, of which I don't know if it's possible with default Forms Wizard; the same field occurs in multiple steps. Is this possible?
