Scalability requirement for WPT tests

This is a question regarding increasing the scalability of the WebPageTest server and agents. We want our build system to be able to reference a single generic location like “Office:Chrome” and have a pool of multiple WPT agents that can all fulfill that location’s needs, so that we can support multiple distinct performance builds in parallel without a queue.

In other words, does the WPT agents have a mechanism to let the host machine know their availability to run a test and pick up a test automatically when the location and browser is chosen from host.
