Hi there,
The latest version of Kutools does indeed support sensitivity labels. To address your issue efficiently, I recommend upgrading to the latest version. This should allow you to work with sensitivity labels more effectively and avoid the need for extensive manual selection.
You can upgrade to the latest version by clicking "Help" > "Check for Updates" on the Kutools tab.
If you encounter any difficulties during the upgrade process or have further questions, please don't hesitate to reach out. We're here to assist you.
