At the moment the Smart Label Function is designed with a "Test" and "Save" - Button. If you want to see, how the amount of clients has been changed, due to the change of your label, you need to click the "Test" Button.

This is the only possiblity to see if you have done an issue or not.

Scenario:
The IT-Supporter is pretty sure that the change he/she made is only a small one and he/she don't need to click the "Test" Button. He/She directly pressed the "Save" Button. Therefore he/she isn't aware about his failure and the Kace starts to deliver the software package to the different machines.

Suggestion:
Independent of the "Test" - Button I would include a function "Overview" which comes up after pressing the "Save" – Button and before starting the installations. You have to confirm that the change you’ve made is correctly.
I would include this for every change which has been made on the Smart Label, but if you dont want to see the overview in non critical changes a "Critical Change" - CheckBox could be integrated.

If this Checkbox has been checked, the overview after pressing the "Save" - Button will only comes up, when the amount of clients, which has been changed, is larger than e.g. 50%
