Combining Nested Schema Transforms in Effect Typescript

I've struggled to find an example of being able to combine nested schema transforms? I've seen the chaining examples

A -> B -> C

A -> B -> C

but nothing that lets you reuse a transform schema for

B -> B'

B -> B'

when you have

A.b

A.b

and want to use the

B -> B'

B -> B'

transform together with the

A -> A'

A -> A'

transform
