Is there a mod that allows Sims to choose a job from any career track, but at entry-level only? I have Monique's computer and Moghughson's Job Board, which are great for most hoods, but my one hood is in dire need of cement mixers and bricklayers, not foremen and heads of construction company! (I guess I should just not have my Sims study so much ).

I'd say the SimBlender.

Thanks, @Essa! I'd never noticed that feature on there and it's perfect!
