Suggestion: Once the sim rejects a trait, never offer it again.

My current sim is at University and keeps getting offered the Perfectionist, Insider and Cheerful traits.. But I don't want any of those traits. 1. I don't need them since I'm already capable of getting my sim there on my own. 2. I'm only getting them because I'm currently in college, being social, joining clubs and trying my hardest to get good grades. After University, I won't need these traits. 

Also, why isn't my sim getting offered Neat, Outgoing, Overachiever or Creative?   My sim is in the arts program and so is constantly creating art. Why haven't I been offered Creative? My sim is constantly cleaning because of living in dirty dorms.. Why haven't I gotten offered Neat? My sim is constantly out meeting new sims and Overachiever seems like a pretty close neighbor to perfectionist. So why not those traits offered?   

At any rate, rejecting the same traits over and over is annoying.
