Do pragmas cover all the operators/nested loops attached under the specified kernel_scope?

Hello! In the GPU conv tutorial I see the following two lines:

s[output].pragma(kernel_scope, 'auto_unroll_max_step', cfg['auto_unroll_max_step'].val)
s[output].pragma(kernel_scope, 'unroll_explicit', cfg['unroll_explicit'].val)

I’m curious if these pragmas cover all the operators/nested loops, e.g. AA, WW in the tutorial, that are attached under kernel_scope which is the first iter_var of output? Generally, suppose I have a schedule looks like this:

for A {
    for B {
    }
    for C {
    }
}

If I set the kernel_scope to be for A, does it take effect on for B and for C? If I want for B and for C to follow different pragmas, should I define two separate groups of tunable knobs for both of them?

Thanks in advance!
