Open Trip Planner 2 - Does it support planning many trips at once?

Question

I'm trying to create a dashboard that simulates the usage of a public transport network for a city by planning many trips at once for a set of different origins, destinations and times.

Does Open Trip Planner 2 support sending multiple plan requests to the server at once or would this require the server to be cloud-hosted for scalability? I'm trying to keep this running locally for now.

I notice there is an AsyncGraphQLFetchers config item but I am not using GraphQL within this project.

I looked through the docs and only found one /plan route without any option for routing more than a single trip.
