Hi, I am hoping that we can have more options for custom format. I would like to use a format with this form [{authors' last name's first letter}{year}]. That is, taking all the first letters of all the authors' last names. For example:

[AC02] Noga Alon and Michael Capalbo. Explicit unique-neighbor expanders. In Proceedings of the 43rd Annual IEEE Symposium on Foundations of Computer Science , pages 73–79, 2002.
