Animating transforms in sequencer

In the longer term, I am still concerned that we will need some custom track work. In the current setup, a lot of classes in MovieSceneTracks are not marked for DLL export, and there does not appear to be a mechanism for hooking into them. Is it possible to have more than one track editor on a single track type? I’m wondering how I would add functionality to existing tracks without just copy-pasting the code and making a new track type. Is there anything in the roadmap that would address this?
