Create Dynamic Table Using Lookup Associated to Field Editor Component

Thanks for responding Matt.  I know this is a crazy use case.  I want the user to be able to add rows to a table in the Exit Interview form (Questionnaire) by performing a lookup against the Account Details object.  For instance, if account number 123456 was part of the exiting relationship, the user would perform a lookup on account number 123456 and from the results, be able to add that account number to the table in the Exit Interview form.  With the selection of that account from the search results, it would add a row to the table that includes the account number and (if one exists) the outstanding balance on the account.  The user would continue this process until all of the accounts associated with the Exit are listed in this table.

The table is tied via lookup to the Account object.
