InField 2.0: Time Interval Mass Deletion/Change

There should be an eas(ier) way to mass-delete or mass-change a time interval. 

Mass Deletion:

• Currently one can select all tasks and ADD a time interval, but cannot select all tasks and delete a common time interval that all of them have.

Mass Change:

• One can replace time intervals, but the replacement HAS to have the same number of time intervals in the desired change as already exists in each individual task. If not, nothing gets replaced and instead the time intervals are added on top of what exists, so you then have to clean up the entire template.
