I have two citations with the same authors and the year of publication;
Law, Boyle, Harris, Harkness, & Nye (2000)

(Law, Boyle, Harris, Harkness, & Nye, 2000b)
and when the other refernece is cited later in the manuscript it appears as;
Could anyone help me with changing the “a” and “b” so that the first citation is “2000a”?
