One essentially to each cover:
- All your production systems
- All your production systems minus the 65 devices.
... the 65 devices can be excluded by including a "AND COMPUTER NAME NOT = 'Device_1'" through to Device_65 (tip - use the "Multi-insert" option to add up to 50 devices at a time).
... If that department has a single identifier for themselves / those devices, it can be even easier. Add a piece of custom data to those boxes and just include a
... AND "Custom Data - My Tag - Special Status" != "I am Special"
There's all sorts of ways of skinning this particular cat. But the above two are two fairly simple ways to approach this.
Does that help?
