Question transitioning between Timeline assets (Timeline asset xfade?)

hey everyone, i'm coming into a situation where i will have 12 cutscenes, each on their own Timeline asset, with all the same track bindings. i want to load up any cutscene/Timeline asset, but have a smooth transition from the current playing asset.

essentially i'm asking for a Timeline asset crossfader, and i would guess that would mean having two Playable Directors sort of like a DJ with two decks, only instead of controlling just volume i'd also be controlling/lerping Transform position and rotation. i've noticed a few videos on Youtube covering Timelines but not sure if any cover how to do this specific task and many of them are several years old so not sure if they are still relevant. any help, advice, or links appreciated!
