[HotChocolate, Projections] How to include navigation property which is not requested in projection?

[Arsync]

For example, we have list of documents. Each Document has a collection of DocumentSpecification (stored in another database table). So after query being projected, there is need to populate Specifications property, which will not be passed to client.

[UseProjection]
public async Task<IReadOnlyCollection<Document>> GetDocuments(
    DocumentsInput input,
    [Service(ServiceKind.Resolver)] DocumentDbContext dbContext,
    IResolverContext context)
{
    var q = (
        from doc in dbContext.Documents
        where
	    // Some of good conditions with values from input object.
        select doc
    );

    // Throws the exception:
    // Cannot apply the 'Include' operation with argument 'x => x.Specifications',
    // ...consider applying 'Include' before 'Select' method call.
    //
    var documents = await q.Project(context).Include(x => x.Specifications)
        .AsNoTracking()
        .ToListAsync();

    var filteredDocuments =
        from doc in documents
        where !doc.Specifications.Any() || doc.Specifications.All(x => x.IsSatisfiedBy(input))
        select doc;
		
    return filteredDocuments.ToList();
}

I know, there is a way to create ObjectType<Document> with always-projected field by IsProjected(true). But how to achieve that behavior for standalone query and not for all other, where Document being fetched?
