Insert customised Art in techpress

While adding new publications in techpress, I see there is an option under general section called “Art” which suggest list of default items e.g Journal Article, Book, Conference, Boolklet, Online, PhD Thesis etc. I need a add my customized items (e.g Whitelist, Publications etc). But i didn’t find option to add it.

Does anybody helps me how to do that? Thanks in advance.
