LyX ⇒ Multi file bibliography?

[00Seven]

Hi there! I currently have Lyx 2.0.3 installed and here's my issue: I have a main lyx document that includes all the chapters of my project, each saved as a separate lyx file. I'm willing to include the bibliography at the very end of the main file, but citations will be inside the chapter files. I pretty much tried everything without good results.. what should I do?

Thanks in advance.
