Customizing Migration Tool to modify items after migration

TLDR: I would like to assign content items to folders based off their class name during the migration. How do I enable ContentQueryExecutor in the Migration Tool? And how to I prevent content items from being migrated with the required PageName field in the content hub?

In the migration tool I have used the "ConvertClassesToContentHub" setting to indicate custom tables that I want migrated to the ContentHub. All of the items are migrated to the root folder, and each item has a required PageName field. I want to modify the logic to migrate the custom table items to the content hub under a folder with their respective ClassNames AND exclude the required PageName field since the custom tables dont have one. I have attempted to add logic based off the ContentFolderService to create the folders but when attempting to load the content items already migrated using this logic (https://docs.kentico.com/api/content-management/content-items) I get the below error:

"Unable to resolve service for type 'CMS.ContentEngine.IContentQueryExecutor'"

How can I include ContentQueryExecutor in the services, am I missing something needed for DI in the program? OR is there some other logic or InfoProvider I can use to load and modify this content hub data in the migration tool, post migration?
