Exception Handling for Time Entries at the Task Level

Product Team,

As a product of our business rules, there are instances where time entries from multiple employees to a single, billable task do not aggregate by a summation.  For example, there are occasions when a client would be billed simply for the duration of a meeting and not the sum of the time each attendee was present at the meeting. In this case, the aggregation of time for this task would be the average. A similar request for this capability was made in the post, Customize aggregation in reports: average Time Spent – Wrike Help Center

However, this request does not seek to substitute an average for summation as the aggregating function. It would be desirable to add a type of billable/non-billable filters at and within the task level to allow for exception handling; i.e., tasks appropriately located within a billable project that are either all or in part non-billable.

Alternative solutions exist such as increasing the depth and/or breadth of the folder/project hierarchy, task splitting, or potentially an aggregation from a custom field. All of these rely on additional and highly contextualized user input which makes these options undesirable.

Thank you for the consideration
