Is it possible to configure a different GraphiteWriter Host / port for each icinga2 Satellite

This question is similar to post Restrict Notifications/Metrics to Master and Satellite - #11 by d33niel

My issue is that each icinga satellite is in a zone for monitoring various host that are associated with different aws regions and what to ensure that traffic flows only into a specific aws region to avoid sending traffic between hosts that are in the different regions. We also have Graphite servers set-up in each region and therefore would like to have a specific GraphiteWriter configuration on each satellite icinga server. Is this possible
