LyX ⇒ lyx and paper templates

[Annicchiarico]

Hello,
I have often to write articles for which I am given specific tex templates.
The template usually consist of a zip file containing:

1) several *.sty files
2) one *.bst file
3) several *.tex files (e.g.: abstract.tex, keywords.tex, authors.tex, paper.tex...)
4) one *.bib file

Is there a straightfoward procedure to "integrate" these files into LyX, so that I would have just to choose the corresponding document-class and not worry about anything else?

Right now, I write the article in LyX, then I export it as latex-source, and finally I copy&paste each section of my article into the template in TeXNICCenter, which honestly I find annoying, because I cannot use LyX to produce the final output. It would be great to be able to do everything only in LyX.

Thanks
