Hey Christian,

this feature does exist (maybe it’s been added in the years) but it’s called: ‘Copy with Property Links’ or ‘Copy with Relative Property Links’.

Select an effect and go to Edit > Copy with Property Links or Copy with Relative Property Links

 

From: https://blog.yarsalabs.com/copy-options-in-after-effects/#:~:text=The%20major%20difference%20between%20Copy,to%20link%20the%20original%20layer.

The major difference between Copy with Property Links and Copy with Relative Property Links is the dynamic ability to link the original layer. When we use Copy with Property Links to copy the drop-shadow effect (or any other property) of Layer 1 of Composition 1 and paste it onto Layer 2 of Composition 2, it will act as an absolute link to Layer 1 of Composition 1. But, when we use Copy with Relative Property Links to copy the drop-shadow effect of Layer 1 of Composition 1 and paste it onto Layer 2 of Composition 2, it will direct or link to Layer 1 of Composition 2.

In short,

The Copy option duplicates layers or assets for individual purposes. The Copy with Property Links option links directly to the original property. And the Copy with Relative Property Links option maintains a link to the original property with a relative offset. All features are useful in different situations, depending on your specific needs.
