Media Framework Trigger Box without Open Source

Using a trigger box I want to have a video start playing when entering the box, pause when entering, and then resume when re-entering the area. Currently, using ‘open source’ the video will restart from the beginning. In earlier versions of Unreal I have used a ‘set rate to 1.0’ when entering trigger and ‘set rate to 0.0’ when exiting. It seems that with 4.16 the set rate for media player does not work and with any other combination of play, pause, etc the Open Source node overrides everything and restarts the video from the beginning.
