Deploy with Reboot or Package dependency

Hi,

i am searching a way to do deploy a package with one ore more reboots in the middle or if not possible, maybe a "dependend" package deployment.

The goal is to deploy more then one piece of software, but each one needs a reboot for the next and after the last i need a "OK". Because it is a timing problem over a lot of devices, it is very difficult to do every single package round by round alone.

Any ideas? THX!
