Allow Custom Date Fields on Calendar

We use a Wrike calendar to track scheduled meetings with customers. However, since calendars can only display due date/start date, we are unable to take advantage of the time function present in custom date fields. The addition of custom date fields to calendars would allow us to order our meetings by time of day like a normal calendar. I have been told that there are no plans to add a time of day function to the due date field, so this seems like a necessary work-around.
