Is there a way to add a background to the marker?

First of all, thank you so much for this library. It has made charting so much easier to work with.

One feature I would like to know is possible though is a series marker could have a background color like the picture below?

Again, thank you so much!

This will be really helpful. Markers often overlap with the candlestick values and become unreadable.
