Yes, if OP finds a school specific app and that might be difficult, but after doing one or two high end schools, the kids will be worn out and begging for common.
Kids are kids - no matter how great, there’s only so much time in the day and they stress. Even with common, for high end schools, this is an arduous process.
Two other points
With individual apps, you’d have to proof read the same areas over and over and over.
Many (public) have additional sections beyond common to re-enter grades - SRAR or something similar - that’s even more pain in the butt work you have to do.
