ProjectWise Navigator V8i - Animating Element Transparency within a Scheduled Simulation

I have created a 4D schedule simulation using ProjectWise Navigator V8i and would like all chosen elements to fade into view as the simulation progresses through the schedule. I have created particular named groups of elements and linked them to start date/time and finish date/time tasks. The start transparency of the named group is set to 100% transparency and the finish transparency to be 0% for each related task. I assumed that as time progressed through the related tasks in the schedule the elements would fade into view, however after the task linked to the named group completes the elements pop into view, they do not fade in at all.

Could anyone shed some light on this one for me please? The only other way i can think of doing this would be to stager the tasks to have multiple start and finsh transparency date/times, however that would be lenghty for the size of model i have!

Thank you for taking the time to read through my post.
