BibTeX, biblatex and biber ⇒ Modify pre-defined style for the bibliography ?

[Davidislm]

Hi everyone,

I have a simple question.. I am writing my thesis in TeX and I was wondering wether it is possible to modify a pre-defined style for \bibliographystyle{} ? I am currently using the style "Chicago" but I would like to add quotes to the article's names and change the option for capital letters in the name of the article ? Also, I use BibDesk to add all my references in a single .bib file

For instance, here is what I get (Ive added manually the quotes for the article's name):

I have mainly two issues: (1) the quotes for articles and (2) the capital letters for all the words I like (to make it like in the .bib file, not only the first one).

I know I can use custom-bib to make the style I want but I was wondering wether it was possible to custom pre-defined style ?

Thank you all for you answer..
