you know what, u can just key in a different ID no. at the first stage and then con't on w/ ur application.. (you may change back your ID no. in the next process of the application)
but ig uess that won't help much b/c at the end, CX still has your profiles..
they say they will only keep for 2 yrs.. maybe all the failed applicants can try again after 2 yrs..
