Linking PDF files in child project

Hi,

I am trying to link PDF files from one child project to another, i.e. Child 1 contains the link, Child 2 contains the PDF.

When I create the link in Child 1, a copy of the PDF is created in assets >docs.

This is making my project too large.

Also when I later make changes to the PDF in Child 2, they do not transfer into the link in Child 1, as the link in Child 1 is actually linking to the PDF it previously created in assets >docs.

Is there any way to link to the PDF directly in the Child 2 project, so I don't have to redo the hyperlink each time there are changes to the document?

I hope this makes sense!
