Set end-date for a timeline

[Erik Lilja]

Hello!

I currently have two timelines, both starts around 6:00 am but both end different. One could end at  1:00pm and the other at 3:00pm.
I'm looking for a solution where i can set a end point for both of them. So, let's say the 1:00pm timeline continues to 3:00pm, but there is whitespace between the last item and the end.

In the image, there is two timelines that end different. What i want for them to scale 1:1-both end and start at the same date.

Is this any achievable for timelines?
