Match reference for already imported PDF
I am sure this has been addressed somewhere else, but I'm banging my head on this problem.
I see how to:
1. Drag a PDF in Citavi, and have the software automatically match the file with a reference
2. Import a new reference, then search for full text
But I don't know how to:
3. If I have a PDF already imported in the Citavi project with no or very partial reference information (title of the file most of the times), how can I match that existing file to the databases, so that the reference information is automatically updated? I.e. in order to achieve the equivalent of point.1 ?
