Feature Request Assign playable to director via timeline

Currently control tracks offer us the ability to progress time on another playable director whichs allows sequencing of multiple playable assets inside another playable asset. However the asset being used by the controlled director needs to be set manually, for example using the inspector or scripting.

It would be a nice feature if we could simply assign any playable asset from the timeline itself. This could be done in the same way that a GameObject is assigned to the control playable. Alternatively having a track that sets a directors playable asset, maybe working like an activation clip, could also suffice. Match content should then return the duration of the assigned playable asset.

All of this would ease combining multiple playable assets into a single sequence. The current way of achieving this is very static in it's nature and combining multiple playable assets is limited to one playable asset per GameObject whilst not using any custom code to re-assign a different asset.
