RoadMap - can we display an image in the place of roadmap step

Hi Experts,

For displaying current Approval status (whether 1 or 2 or 3), I created a Road map with 3 steps.

Based on Approval status level values (1,2,3) , corresponding Road Map steps enabled.

Is it possible to display an icon/ small image ( For ex : a Tick Mark ) in the place of Road Map steps 1,2,3.

i.e it should be displayed as

thanks
