Multiple task bars in screen type

Currently it is not possible to add multiple task bar components within a single screen type.

I'm creating a wizard and want the goto previous task to be on the left side of the screen and the next task on the right side of the screen. After placing two task bars on the screen type and saving them, there is no way to indicate on which task bar a task will be placed.

Currently a single task will then be placed in both task bars. In the Windows GUI this looks like

My wish is that just like details, it is possible to assign a "detail group” (or in this case maybe a task group, even though that then has a double meaning), both in the screen type as for (linking) table tasks. In this way you can indicate in which task bar a task will be placed.

Naturally the vertical alignment issue should also be resolved.
