Allstar cheerleading in ts4

Im an allstar cheerleader myself and grew up playing the sims. I always wished for a way to become an allstar/competitive cheerleader in the sims. I've tried to open an allstar cheer team through the get together group feature but it just doesn't feel right. I know that we have cheerleading in the high school years Pack,but it doesn't give the excitement like allstar cheerleading. I would love for a pack to be around competitive cheerleading. Having practices,doing Stunts,creating a routine,beautiful uniforms,going to competitions and winning trophys. It could work like the job feature or after school activities feature. Important for me is,that it's not only for the teenager lifespan, since many allstar/competitive cheerleaders are of age.
