MSCommNet Non-Affiliate-Scan Multiple Sites

[EasternMassScanFan]

I am using an APX 7000 to do a non-affiliate-scan with MSCommNet. I was wondering if anyone knows how to program properly multiple MSCommNet sites so you don't miss traffic. When programming three sites in with their various control channels then sitting on the conventional channel that the talkgroup scan list is set to, I missed traffic.
