Unfortunately not, as this will affect all future occurrances as well. What i am looking for is that only the current occurrence is postponed.
For example, say i have a task that repeats every 1st day of each month. Now i can't always do this task on the first, sometimes its the second, or the third, or .... So i want to be able to postpone THIS OCCURENCE ONLY and put it 1 or 2 days later. But when it is finished, i want it next month on the first day of the month again.
Hope it is clear now.
