Yes, if you're running a CSA Management Center then you can customize your own policies and generate new agent kits, either standalone or managed. Export files are available from the CSA for Unity and CCM 4.x standalone agents. You can use these export files as a starting point for new policies in your CSA MC. Customize the policies as needed then generate new agent kits.
The export file for Unity can be found here:

Hope this helps,
