how is everyone tracking when a CTA changes stages from New-in progress-closed?

Hi Denver - you'd have to have your IT team enable history tracking on the Call to Action::Status field. Then you could build a Data Space starting with the History::Call To Action object, making sure to pull in the Account Name, Account ID, etc. from the Parent ID -> Account object , (and any other fields in the object hierarchy you may want to capture) then create a report off of that data space showing you the field that changed, the old value and the new value..

I am not tracking the Status field myself, but here's an example of what a similar report built off of a data space created using History:Customer Info as the base looks like. The Changed Field = CS Segment - but in your case you'd use Changed Field = Status:
