Automate Patch Deployment - Scan at startup and install at shutdown?

Hi all

We use the Automate Patch Deployment feature (Scan systems, download and deploy approved missing patches) to scan all systems on a daily basis and install any missing patches which were approved before.

If a computer is not switched on at the time the task runs, the missing patches are obviously not going to be detected and not installed.

Is there an efficient way to circumvent this? As an example, is it possible to configure the automate patch deployment task to scan the computers at startup instead of a certain time?

Also, is it possible to install patches at shutdown? The install options only allow installing patches at startup or during the refresh interval.

Thanks & Regards
Stefan
