You need to provide a concrete example in order to get a reasonable
answer.

In simple macros like this one,

   (define-syntax let1
     (syntax-rules ()
       [(_ x e b)
        (let ([x e]) b)]))

   (let1 x 1 (+ x 2))

CheckSyntax will draw an arrow from the x in (+ x 2)
to its binder without anything special.

If you somehow manipulate the identifiers, then the
answer is "it depends".
