Approval SLA Reporting

Need the ability to capture the SLA for each Approval flow in CPQ.

We have multiple approvals in CPQ. There are serial approval and parallel approvals. I need to capture the time a quote sits in a particular approval.

Start time: when a quote is submitted for approval

End time: when a quote is approved

This may happen multiple times and there may be back and forth. I want to capture all the instances.

I want to get this at individual quote level and also at entire CPQ application level. This will help business understand where the time is spent during quoting process.
