Can I change lines to dots in a clustered bar combo chart?

I’d like to make a graph like the first picture shown but rather than have a connecting line I’d like to just have the markers. I know how to do this on a regular line graph but not a combo chart. Is this feature allowed on combo charts? If not is there a work around?

I don’t think this is possible and could not find a work around for your use case.

I will mark it as a feature request.
