Few, if any, schools will highly value an amalgam of community service hours. If she is able to focus more on areas of interest to her and that support the overall narrative of her application, that will be more valuable than a mish-mash of school/community/religious activities that happens to add up to enough hours for an award.
Certain schools will value community service more than others, but even those schools want to see thoughtfulness of purpose, initiative, and creativity in which projects an applicant has pursued. Rather than worrying about achieving a certain number of hours, as she gets into her upper class years she should focus on being intentional about the community service. All schools will value that kind of initiative and maturity.
