restrict Auto-conversion to certain formats

[wookielover]

Good day everyone! Here is my issue. I download tons of books using an RSS feed.I have Calibre setup to auto-add books and convert them to EPUB when they are placed in a particular folder. Is there a way that I can have calibre set to only convert Mobi, LIT, AZW, and a couple other formats and not convert but still add, PDF, CHM etc to the library. PDF files do not convert very well, but i would like to still have them added when i do download them. Is this possible?

in the global.py file there is a section :

# Ordered list of formats to prefer for input.

If i just remove the formats I do not want would that do what i want it to?

If this is somewhere else please point me to it as I could not find this anywhere..
