Smart links are not updating or working in the combine process

[jesusdp]

Let me explain the two scenarios where we are using the links to refer a different sections in the PDF.

1.- If the links and the sections are in the same PDF generated those are working properly as expected.
2.- If you have multiple PDF's and combine them in the following way:
2.1 .- PDF 1 Generate links to X, N references. Those references are not included in this PDF but they will be present in the PDF 2.
2.2 .- PDF 2 Include the references.
The output in the point 2 is that those links are not working and unable to click them. Please advice.
