How to kick off multiple approvals and update SharePoint when they are complete

[Smitsky34]

I have a request to create and capture an employee acknowledgement for company policies.  Every employee must acknowledge every policy.

I've created a flow that reads a library of policies and also reads AAD to get a list of all the active users.  I then write a record to an employee acknowledgement list with link back to the policy.  One thought was to have the users go to the list view with pending policy approvals and click a radio button that they acknowledge the policy and enter the date of the acknowledgement.  I tried to use the field validation in SharePoint to validate that the date was today or in the future but when I do that the record can't be written with a blank date so I can't even create a record with that column validation.  So I'm thinking the only way to capture the date systemically would be through an approval workflow.  The problem with the approval is there is "Send and wait for an approval" and "Create an approval"/"Wait for an approval", either one I have to wait for the approval to complete so I can get the information back in the flow from the approval to set the date of the acknowledgment back in SharePoint.   The problem with this is there are 38 policies and 117 users, so I can't wait for all users to acknowledge one policy and then move to the next.

Is there a way to reference back to the approvals in the dataverse / CDS so I can "Create and approval" in the flow, write some value to the acknowledgment record pointing back to the approval in the dataverse so I can reference the approval after some time, maybe a nightly flow that looks at the acknowledgement list for all the records that haven't been acknowledged, find the value from the list and then find it in the dataverse to see if the approval is complete?  If it is complete, take the date and insert it into the list with the radio button acknowledged and move to the next.
