We name computers a special way. Anything that ends in "-TC" is a "Thin Client". These machines can be patched and rebooted nightly. So i created a dynamic group matching on "Computer Name" ends with "-TC". I have then two patch policies. One that's "Patch Nightly with Reboot Prompt" and the other "Patch Nightly Force Reboot". All computers are in the first patch policy with dynamic group "Thin Clients" filtered out. I now want to assign the "Thin Clients" group to the second patch policy but cant because it's a custom dynamic group.

How do I accomplish this now?
