refer from inner `with` function to higher level `with` function

In my code I have a struct like this

post { req ->
    with(req.objectBody<Person>()) {
        logger.info { "Attempt to save person $this" }
        with(require<SessionFactory>().openSession()) {
            save(this@with)
        }
    }
}

But IDE warns me that there is more than one label with such a name. In this case

save(this@with)

I want to refer to with(req.objectBody<Person>) instance. How to achieve that?

Technically, you can mark lambdas with custom labels and then use labeled this with those labels. such as:

with(foo()) mylabel@{
    with(bar()) {
        baz(this@mylabel)
    }
}

However, to improve readability, instead of with, you can use the let scoping function and provide a name for the parameter:

foo().let { fooResult ->
    bar().let { barResult ->
        baz(fooResult)
    }
}
