I am a bit confused with what you need. Do you need web form steps to be clickable? or creating a custom web template representing each tab?
I don't think we can create web form steps clickable as this might mess up with the web form session transition path (necessary to use the previous/next feature).
about something more custom, you can create multiple entity forms and each one would be redirecting to the "next entity form". if you need to jump to a certain "step" this will simply be another entity form
but pay attention on how you are going to treat the previous/next here, for example:
Step 1 --> Step 2 --> Step 3 --> Step 4 --> then user goes back to step 2 --> previous button here will be step 1 or step 4? this needs to be defined in your logic
