College App Fee Waivers

I’m confused about fee waivers. I have 4 fee waivers from College Board, but the UC App website says that they have their own application to request fee waivers. Does this mean that I can apply on the UC App, get 4 fee waivers, then use the 4 College Board fee waivers on the Common App? Or do the 4 fee waivers span across all apps?

From the UC Website:::
Fee waivers

UC will waive application fees for up to four campuses for qualified students who would otherwise be unable to apply for admission. The fee waiver program is for United States citizens, permanent residents, and applicants eligible for AB540 benefits.

Fee waivers can’t be applied to more than four campuses, regardless of their source (e.g. UC, CollegeBoard/SAT). If you apply to more than four, you’ll need to pay $70 for each additional choice.

Applying for a fee waiver:

You can apply for a fee waiver within the online application and be notified immediately whether you have qualified. You will need to provide your family’s income and the number of people supported by that income.
