[Maria-discuss] replicate to multimaster

Hi, I have a single Mariadb server 10.1 on Ubuntu 14.04 and 3 Mariadb 10.1 servers on Ubuntu 16.04 with multimaster setup (galera). Is it possible to setup replication from single server to one of multimasters to keep databases and grants updated on multimaster servers? Or should I export databases and grants from single server to any member os multimaster servers? Thanks for any tips/hints.
