download the PAR2 files with the RAR's??

[LGS_Corp]

sometimes, I want to download all of the RAR's and the PAR2 files and save them, for example, when I am downloading a rare film. Recently, someone posted many files that I want all of the rar's and PAR2's.
How do I set NewsBin to automatically grab the PAR2's as well as the RAR's?
