Planner Items vertical in orientationMode=Horizontal

I would like to use the TMSFNCPLANNER with "pomHorizontal" and mode "Day Period" in my app. However, the appointment entries of the resources should be displayed below each other and not next to each other (see ScreenShot). Is that possible?

They will only display below eachother if they conflict, which means they have date/time overlap.

Hello Pieter,
thank you. This is the solution.
In this view of the app, the exact time period does not matter. I simply equate the initial time of the items per resource. And already the appointments are among themselves. Perfect!

Thanks for your feedback!
