Duplicating track matte & parent should have different behavior

Hi I absolutely love the new track matte system!!!

Kudo's to the devs its a really really nice change.

However one thing was lost in the new system, previously when you copied a layer and the layer it was trackmatted to the trackmatte updated to fit the new layer. Atm it isnt like this. I included a video with an example.

(Its kind of hard to describe properly since my second language is english)

What would be ideal is that AE checks if the track matted layer is also being copied and makes the new copy automaticly update to the new one instead of the old one.

If this description is kind of confusing please watch the video it makes it a bit more clear.

Much love,
