How to add relationship to the *.drw file with *.pdf?

Hello everyone!

This is my first discussion subject, so be patient with me.

I would like to add relationship to the *.drw file with *.pdf made of it.

For example:

I create in my workspace pdf from drw drawing. I want that pdf follows after drw wherever it goes.

In old version it can be set manually by add it in Reference. Now I have Pro Intralink 10.2 and that option is not allowed.

How can I add Reference? Is there any way to set it automatically?
