Place Precomp using relative link
I have a project folder, and inside that project folder I have a Main Composition (A). On a layer in "A" I have a Precomp (B) that contains some video.mp4 (C). The Precomp (B) is located in a project sub-folder next to the Main Composition (A). So:
PARENT_FOLDER:
↳Main Composition (A)
SUB_FOLDER:
↳ Precomp (B)
video.mp4
I want to be able to duplicate the PARENT_FOLDER and have the link to the Precomp (B) inside the Main Composition (A) be relative, so that it's linking to whatever Precomp (B) is in the "SUB_FOLDER".
That is to say, I don't want to have to constantly relink the embedded Precomp to the new one created by duplicating the parent. Is there a way to place a Precomp into a timeline with a relative link?
