Apologies for the late reply - I have been away on my Holiday :-)
As Craig said, there is nothing in the hour for Myriad to play with (i.e. drop / fade early). Any fixed carts or links are tagged as non droppable or fadeable.
In Myriad v4 Station Database settings you change this functionality as it can be quite dangerous - this is a blanket setting so if you allow dropping of links and you schedule sponsor mentions in a link category these could be dropped or faded.
If you have a pre-recorded set of items that you need to fade, make sure the programme supplier has either back timed perfectly (but they may not know how many ads / promos you have scheduled) or to leave a couple of songs at the end of the final segment in the hour.
You can use the above clock setup to schedule, when it arrives in the Myriad Log, right click over the Link or Cart Icon and change it to a Song which will be faded to get to the time marker.
