Flow Formatter/Progress Bar change first state

Hi everybody! I have created some custom states for the task table, and I've add a flow formatter (process bar of the states) on the top of the task form. Now I would modify the beginning of the progress bar, for ex. if a users click a button, the first state will be one, if they click another one it will appear the other one as first state. (The other states of the process bar will be the same, only the first one will change)

I have to do it with the flow designer or I can also do it with some policy/br?

Thanks
