Is this for a specific set of users like your DBAs?
Can you create a custom property for those nodes say for example call it subplot. Then assign the term Production SQL Servers to that property.
Then under the filter you can say Subplot = Production SQL Servers
Thanks guys, as I said I am new to Solarwinds ... Actually I solved it by getting familiar with the magic of custom properties and and I am assigning custom properties to each node and I am able to filter based on the custom properties. I have removed the group as a consequence...
