Milestone (Vertical) - skipping a step

Hi All,

Does anyone know if its possible to skip steps in a vertical milestone? What I mean is that the stamp can stay grayed out based on a value, and then if it was skipped only the first and third would be green, is this possible? I have tried a few things but it still keeps the linear flow.

Like in this case if I went from claim filed to estimate issued , all 3 stamps are green, I would want Green - grey - green because technically the second one didn't happen.

or another option could be to hide the middle stamp too. but not sure if that can be done.
