How to rollback more than one coniguration steps

Hello
I am new with Icinga director and made a mistake with a loop in a service template. But this is not the question.
I understand the deployments as transactions of particular configuration steps. The steps are in the activity Log. Now I’d like to rollback to a point in time where the config works. Like git checkout .
But it seems to be that I can only restore particular objects, is it right?

Cheers
Heinz
