访问先前执行的查询的结果

I have a nested relationship and I would like to filter them, using the result that comes from the first query run by Eloquent.

My Eloquent query is:

$entry = Entry::with([
            'products.unit',
            'products.area'
        ])->find($id);

The query log shows me that Eloquent runs this query first: select * from entry where entry.deleted_at is null and entry.id = ? limit 1

And I would like to use its result in this second query, also run by Eloquent:

select area.*, 
area_product.product_id, area_product.quota as pivot_quota,
area_product.month as pivot_month 
from area inner join area_product 
on area.id = area_product.area_id 
where area.deleted_at is null and area_product.product_id in (?)

I would like to put a constraint inside it using the month value that comes from the first query.

Is there a way to do it using Eloquent?

I was thinking in something like this:

$entry = Entry::with([
             'products.unit',
             'products.area' => function ($q) {
               // using month here!
             }
         ])->find($id);
