Sequencer: Trigger an event from within the sequence without trigger event keys?

Hi-

I’m attempting to create a level sequence as a template sequence, with an event to trigger at the end of the sequence. As a template however, the length of the sequence can vary - so I’m trying to determine how to fire an event when the sequence ends, without keys in an Event Track and from within the director BP itself.

I’m wondering if the above is possible - most of the BP nodes seem to control sequence playback (play start & end) as an external component and not from within the sequence that’s currently playing (at least from what I understand of it).

Any help or tips would be appreciated!
