4.12 Add Blueprint variable in sequencer

How do I add a Blueprint variable track in the new Sequencer? I converted a preexisting Matinee to Sequencer and the process did produce tracks in the generated Sequencer with the variables and values for the Blueprint variables I was controlling in the Matinee, but they don’t seem to work. I was trying to recreate them but I can’t find a way of doing it within the Sequencer editor. In the Blueprint, under the variable settings I can only see “Expose to Matinee”.

To answer my own question, the variable had to be made public (in Matinee wasn’t a requirement) and also have its “Expose to Matinee” property selected, even though this is for Sequencer (maybe this should be renamed?)

I’d love to know if there is a way to have the variable track visible in the sequencer by default. Right now The only way I see this is to manually add the track on the blueprint object. And since we can’t copy/paste a track, it makes it hard to setup a workflow for other artists to use custom blueprint events. Any way to do this?
