Enhancements to PEOPLE fields for conditions

The only way to filter people fields on start events or query a list is through ID, which I have found no way to get ID in a workflow if this isn't originating from a SharePoint list item.

The objective is simple:

Query all list items where user is listed in 5 different people fields. We need to verify that the user submitting the form (NAC Start Event form) isn't already registered and on a team (teams make up max of 5 people hints five separate people fields in sharepoint list).

Request:

Please include people email, display name and user name like we have in the objects for the output of information but into the conditions parameters. I now have to create five (5) text fields in sharepoint list to store the email of the people in the five people fields!
