Replication Interval aka Repeat Every

I have searched this forum and technotes to no avail. I have been trying to deploy a policy to end users to force their replication interval or “repeat every” (interval is the field in the location doc) to a value such as 60 minutes. Some of our users are setting it to 5 minutes or less. However, after reviewing technotes 1106153 and 1196837, that variable cannot be set unless there is a notes.ini variable. I have yet to locate one. We do not want to rely on sending users code in an email, or modifying the mail template. Any ideas? Thanks!
