It seems that in LaTeX, it is not generally possible to preserve the hyperlinks in an included PDF (see e.g. "How to preserve hyperlinks in included PDF?").
However, I was wondering: Does this feature exist for LyX specifically?
And if not, how difficult would it be to implement it? (I should like to submit a request for such a feature.)
In Adobe Acrobat it is a very simple matter to insert PDF with hyperlinks preserved, so I am not sure why this is difficult/impossible to do in LaTeX or LyX.
