Feature Request: Policy for Randomized Scheduled Scans for Endpoints and Servers

I would like to see a randomized scheduled scanning option for servers and endpoints in the policy.  For instance, "scan once a week or once a month between these hours on these days".  I want to scan my servers and endpoints, but I don't want them all to initiate their scans at the same time.  This is especially important because of virtualization, I don't want all the machines on a particular virtual machine host to all kick off a scan and create untenable levels of disk contention.

Thanks,

Eric
