I went to Admin \ Custom group \ Create New \ " Dynamic"

The I selected "Software name" - "not equal" - "7-Zip 15.14 (x64 edition)"

So now I have a dynamic group set with all pc's that dont have 7zip. I checked and this does update itself.

Then I create a configuration, then I select "Apply to Specific Target" and pick "Dynamic custom group" and pick my 7zip group I made above.

When I deploy this it will install to any machine that doesnt have that software.

The problem is, it does not periodically reset the configuration with the updated dynamic group information. It will just mark a computer as  Succeeded but never check it again. If a user uninstalled the software, the configuration would not try and deploy it again. 

Is there a way to make a configuration continuous? so that it automatically deploys itself every few hours? Then the configuration would be dynamic too.
