Meaning if I want to push an Apple VPP update to all enrolled devices, clicking the "Select All" checkbox only applies to the first 100 (as the ceiling).

We currently only have 105x macOS devices enrolled, but are in the process of bringing over 850x others from VMWare Workspace ONE in a way that's "zero touch" for the user.
You can imagine us having to click the "Select All" checkbox on each 9x pages containing 100x devices/each would be inefficient.

Screenshot is from my work Gmail and is just an example of what I would see implemented.
