Replication Formula - role out to multiple users?

I have searched this forum and do not find a solution. I have 1 server and multiple mobile users with local replicas of a database. I want to be able to update the replication formula of the local replicas of this database? (without having to manually do it). The “Replication Settings”, “Advanced” option allows “When server…” recieves from “Server …” etc… , but how do I allow LOCAL replicas to receive a replication formula when it changes? The formula will be the same for each user.

Thanks
