Original Enrollment Date - can you report on org enrollment date of the Plan and not just the option

Is there a way to report on the original enrollment date of the plan and not just the option?  For example if the employee originally enrolled in the Plan, Great Medical; Option Single on 01/01/2020.  The original enrollment date is 01/01/2020.  On 3/1/2020 she changes to Plan, Great Medical; Option Employee + Spouse.  The orignal enrollment date changes to 03/01/2020 because the option changed.  Is there anywhere the system records the orignal enrollment date in the Plan Great Medical.  Or is there a simple way to capture this in reporting?
