A way to override title data from server API during experiments

For example, we're running an experiment where we've divided our players into 4 cohorts and have a title data override for each cohort. The title data is read by our custom server (using the server API) and is used to grant initial inventory. Right now we have some temporary code to override the title data based on certain factors but it would be cleaner if we could rely on the experiment system to do this for us.
