freebsd-update: holding back patches, or to a specific version

[Derek (freebsd lists)]

Hiya!

Was wondering if anyone knows a way to *not* update to the latest 
patch level, but a specific patch level with freebsd-update?

I can see some docs available around rolling our own 
freebsd-update server, and that might be the route we go, but it 
would seem like I should be able to select a point-in-time, as 
long as it is ahead of where I am now?

Any thoughts welcome, thanks!
Derek
