Matinee and old InterpActor sound functions

Hi,
In ye olde UDK you could embed SoundCues for Open sound,Opening Sound,Opened Sound,Close Sound,Closing Sound,Closed sound into an InterpActor and these would automatically get called by the Matinee start points and end points (and when it reversed). Although you can now make any static mesh movable these options appear to be missing - which is a shame as it was a rather simple and elegant solution. I’m aware that I could probably achieve similar by using event tracks and a Matinee Controller in blueprint to construct something similar (although it might be tricky to get notification of reversing ?) but this is going to be a bit of a chew. Are there any plans to re-instigate anything similar before I attempt this ?
Cheers,
R.
