at the moment it is only possible if the ruleset itself is able to manage a list of requests and a list of response.
You would still send one request and receive one response, but in the requests you would have a list of parameters and in the response a list of results.
This require to create a loop in the ruleflow to evaluate individually each request
I can only suggest you open an RFE for asynchronous requests execution if you think it would be useful for your usecase here
