Smart group to remove from SLA count hosts without schedule policies

Hi team, 

We are on the way to make SLA Report more consistent by remove not scheduled host.
Looking for any suggestion how smart group should looks like ?

1. Create one manual group for all schedule policies and second smart 
   client association to the schedule policies - not equal - [previous create SP]
   Or...
2. Client by schedule interval - equal to - daily 
   
   For all above situation  advance settings KPI → Exclude from SLA
