i'm not sure I understand your question.
hop flavor and aroma is not something that any brewing software that I have ever seen accounts for. the only thing I've seen is the bitterness calculated for you. late hops and dry hops add no bitterness. Hops have to be boiled for bitterness to be obtained from them, so late hops and dry hops will not impact the IBUs of a neer.
