Hi again Titus and list

so the semester is finally nearing the end which means i finally have some time (and a life :)) to get back to what i partially started a few months ago.

i have a question regarding Predefined searches. i have a search that works well for searching papers i authored. 
i am thinking of moving towards 2 bib files instead of 1 big one, that is one for my papers and one for the rest (any disadvantages of using 2 bib files?).
i want to add in the Predefined search to only draw from my file (mypaper.bib), even though in the default helm-bibtex sources it will have 2 inputs. is such a thing possible?

this is how a current search i have looks like

#+BEGIN_SRC emacs-lisp :results none

 ;; Define helm-search with predefined search expression:
 (defun helm-bibtex-ikloog-publications ()
   "Search BibTeX entries authored by me"
   (interactive)
   (helm :sources '(helm-source-bibtex)
         :full-frame t
         :input "kloog !unpublished !prep "
         :candidate-number-limit 500))
#+END_SRC

how does one add the specific .bib file filter?

best

Depends on what you mean by customizable.  If you mean a customization
option to allows you to replace the function for APA formatting with
another function, then yes that would definitely make sense.
