Is there a way to change the colors of the vertical markers in Roadmap Planner?

[Jozi Brennan]

When creating my Roadmap Planner, I have added vertical markers for milestones. I would like to be able to change the colors of the vertical markers to easily distinguish between my milestones. Especially when I have a lot of horizontal bars on my roadmap and have to scroll up and down to see the dates, this becomes an apparent problem.

I am hoping someone will pipe up with a customization for this but in addition I think it would be a good in-product feature:

As a user I would like to change the marker colors on the Roadmap planner

Please vote on the ticket I created ^ and explain your use case in a comment to help get the attention of the development team.

You can already edit the markers to change their names so it would make sense to be able to change the color at the same time.

I am using a hack, simply add another marker to get a thicker or double line.  Hope this helps
