Cancel only one reoccurrence

We have several reoccurring task set up. For example, one member of our office has a meeting every Wednesday afternoon from 1 to 3. This week the meeting was canceled (but the following weeks the meeting is still to happen). When we changed the status to canceled, it canceled the whole recurrence instead of just that days. We went back and changed it to complete, but this doesn't give us an accurate account of what happened. Is there any way to cancel a single occurrence of a reoccurring task? If not we would like to see this feature added in the future.

At the moment you can do the following:

1. menu Tools / Custom Workflow / Edit Status 'Cancel' / set its completion 100%

or

2. right click on a task, select 'Roll up recurrence task', then double click on the task you wanted to cancel and change its status to Cancel
(all other tasks will not be changed)
