Filtering and data loaders usage

[trojanmartin]

For our backend REST API we are using HC graphql as BFF. Is there any way to solve the following situation using data loaders?

Let's say we have 2 services, Product and Price service. Our BFF has a graphql query that allows filtering by product number, price range. If the query contains a filter for the price range, we need to make a query to the Price service to filter the products prices in the desired range and then go to the Product service to retrieve those products.
The Graphql query returns a product, but the product object from the product service is extended to include a price and is retrieved by the PriceByProductNumberDataLoader. And here's the problem. We are querying the price service twice. The first time because of the filter, the second time because of the product extension. Is it possible to reuse the answer from the filter request in the data loader?
