Yes, you can pull in the event coordinator's name for a TeamRaiser using the following syntax:

[[S47:xxxx:fr_info:1:coordinator_name]]

Where xxxx is the fr_id of the TeamRaiser. Note that if you are using a Blueprint and placing this S-tag in a locked field, use the fr_id of the Blueprint itself and when you push changes to child events the fr_id of the child event will be used automatically.
