I would like to be able to assign a task to a taskbar like we assign details to a detailgroup. I want to be able to show other tasks in the taskbar above the grid than the tasks on the form.  

In case we use 2 taskbars in the same screentype you get all the tasks in both bars (see Any ideas/tricks to running tasks from different parts of the same screen?) .

It would be easier to assign the tasks to the ‘taskgroup’ of the taskbar. Maybe It could also be used to omit tasks in the taskbar (see Configure task, report and prefilter bars). 

The same could apply for reports.
