Custom Roadmap, mix of Bars and Dots

Need ability for custom roadmap to show bars for initiatives that have defined end date and some other treatment (e.g. dots) for initiatives that are in future but have no end date defined. E.g. Status is backlog, or assessing/estimating.

This was possible on roadmap until 5/29/20, an Initiative with start/end date showed as bar. An initiative with start date but no end date showed as a dot. This made it easy to show 'placeholders' on roadmap, that were visually different. As of the 5/28 release these now show as bars. Does not clearly distinguish them as end date not defined.

We want the bars but perhaps there could be a different visual based on status.
