Is there a way to query a role by model class and resource id, instead of running a query for the resource?

For instance, I want to find out if the user is an admin of a certain company:

2.3.3 :035 > user.has_role? :admin, user.company
  Company Load (0.4ms)  SELECT  "companies".* FROM "companies" WHERE 
"companies"."id" = $1 LIMIT $2  [["id", 3], ["LIMIT", 1]]
  Role Load (0.8ms)  SELECT "roles".* FROM "roles" INNER JOIN "users_roles" 
ON "roles"."id" = "users_roles"."role_id" WHERE "users_roles"."user_id" = $1 
AND ((((roles.name = 'admin') AND (roles.resource_type IS NULL) 
AND (roles.resource_id IS NULL)) OR ((roles.name = 'admin') 
AND (roles.resource_type = 'Company') AND (roles.resource_id IS NULL)) 
OR ((roles.name = 'admin') AND (roles.resource_type = 'Company') 
AND (roles.resource_id = 3))))  [["user_id", 6]]
 => true

That first query is a waste, since I don't always need to look up the company. Is there a way that I achieve something like the following?

2.3.3 :035 > user.has_role? :admin, Company, user.company_id

I want to avoid the user.company call that hits the database, because the role lookup only needs to know about Company and user.company_id.

The above example gives the following error:

ArgumentError: wrong number of arguments (given 3, expected 1..2)

So this would be a non-breaking change if it was implemented.

OMG, I'm looking for this too. But a year ago.
So, I end up with a trick like this
user.has_role? :admin, Company.new(id: user.company_id)
