Delay until a event of sequence has finished in UE4

Question

Hi there,

I was just wondering if there is a way in UE4 for delaying an object until an event has finished playing. For example i have a post event at location and i want something to happen once the event has finished, but the time of the event changes depending on the random combination of the audio files in the event, so i cannot just delay for X amount of time because the time is uncertain. If i was implementing directly into UE4 i would bind on event audio finished, but i cannot think of a way to do this with the post event at location node!

Thanks!
