Geo IP Ideas/Requests - different spam outbreak policies by Geo IP

I'm really liking the new Geo IP functionality in FortiMail.     The additional data is helpful for analysis and policy generation.  However, I'm finding that a few of the things I'd really like to do aren't in there yet.  Specifically, the Spam and Virus outbreak feature would be great to apply differently based upon the GEO IP, but right now they're done at a global level.    

In my case I'd like to be able to create a policy that takes mail from particular GEO IP's that we don't typically get mail from, and run those messages at a higher level of Spam/VIrus outbreak, and also to hold them longer, since they're inherently a bit more suspicious.
