Questions about PLAYBOOK integration

[devpc]

Hello there, I have few questions about the Playbook, I'm starting to using it and I want to understand somethings.
1) Is it possible to restart again the playbook if I'm in the middle of the process? For instance if I notice that some step are wrong in the process or something else, how can I start it again?

2) How does it work in scoped application and workspace?
I've created a dedicated workspace for a scoped application and I want to implement the playbook in it, but I'm having some difficulties here since it wont show on this dedicated workspace, only on the "Service Operation Workspace"

3) How can be integrated with REST and API call? Is it possible do it right now?

4) In the middle of the process, is it possible to assign the playbook to someone and can only him work on it?

5) I saw that in the WORKFLOW STUDIO HOME there's a "Operations" section where I can see two charts, Most executed playbooks (this month) and Playbook executions by state (this month) (see picture below), is it possible to integrate more charts? Is it possible in the specific to make a report on how long it takes to complete the steps in the Playbook?

I know that there are a lot of questions here, so pardon moi 😁. Thank you everyone
